The evolution of airborne electronic warfare systems.The Evolution of Airborne Electronic Warfare Systems
Hide-and-Seek is Becoming a Very Difficult Game to Play
Many aspects of airborne electronic warfare had their origins in WWII WWII
World War II
WWII World War Two , but in the early post-war period there was a hiatus, until the first American jamming pod suitable for tactical fighters was delivered in 1956. The escalation of the Vietnam War at the end of 1964 brought a sudden demand for modern EW equipment, primarily because of the introduction of SA-2 batteries around Hanoi in early 1965. To reduce the SAM threat, US aircraft were equipped with radar warning receivers (RWRs), and some later had jammer pods and chaff-dispensers. Strikes were supported by EB-66 jamming aircraft and F-4 "chaff-bombers", as well as by F-100F, F-4C and F-105G Wild Weasels using anti-radiation missiles (ARMs).
Other nations lagged behind. When British forces went to the South Atlantic in 1982, Harriers had RWRs but lacked chaff dispensers and jammers. Anti-radar strikes were left to the Vulcan, using Texas Instruments AGM-45 Shrikes, and Westinghouse ALQ-101 jammer pods. The Israelis were meanwhile using electronic warfare on a large scale in the Lebanon, attacking Syrian SAM sites with virtual impunity. The same applied to US strikes against Libya in 1986, which involved the Texas Instruments AGM-88 HARM and Shrike shrike or butcher bird, predatory songbird found in most parts of the world except Australia and South America. The plumage of the European and North American species is mostly gray, black, and white; the tail is long and rounded, and the wings , and support jamming by EF-111As and EA-6Bs.
Before reviewing the main types of EW equipment on a country-by-country basis, it may be useful to outline the principal lines of current EW development.
The term ESM (1) (Enterprise Storage Management) Managing the online, nearline and offline storage within a large organization. It includes analysis of storage requirements as well as making routine copies of files and databases for backup, archiving, disaster recovery, (Electronic Support Measures) is generally used to indicate the passive identification and location of emitters, using relatively sophisticated equipment, possibly with data-recording facilities. A simpler form of passive equipment is the radar warning receiver (RWR RWR Radar Warning Receiver
RWR Ronald Wilson Reagan (40th President of the USA)
RWR Royal Winnipeg Rifles (Canada)
RWR Reword (proofreading) ), which indicates to the pilot the type of radiation to which his aircraft is exposed, the relative bearing of the transmitter and possibly its range and operating mode. In US terminology RWRs come in the AN/ALR series, e.g., the Magnavox ALR-50 that is fitted to several types of US Navy aircraft.
In essence, a number of small antennae are linked to a bank of receivers, each tuned to a consecutive slice of the waveband wave·band
A range of frequencies, especially radio frequencies, such as those assigned to communication transmissions.
Noun , thus allowing the radar type to be identified. Its bearing and approximate range may be established by comparing the signals received by the different antennae.
Adequate threat warning may be provided by a simple crystal video receiver, but increased sensitivity can be achieved with superheterodyne receivers. However, their greater range results in more data, and thus calls for a more capable threat processor. One example of such equipment is the Loral ALR-56 series of RWR with programmable processor used on the F-15.
Threat warning systems are currently being extended to cover different bands, such as lasers, IR (for missile launch warning), millimetre-wave radar and even ultraviolet. Warning systems are also being linked directly to countermeasures, and in some cases the two are being developed as an integrated system.
Laser warning systems are receiving considerable emphasis for several reasons. Most tanks now have laser rangers, and many air defence guns are being equipped with automatic electro-optical tracking and laser ranging. In addition, laser guidance is gaining in popularity for SAMs, as illustrated by the Oerlikon/Martin Marietta ADATS ADATS Agricultural Development & Training Society (India)
ADATS Air Defense Anti-Tank System
ADATS Army Development and Acquisition of Threat Simulators
ADATS Airborne Digital Avionics Test System . Laser warning equipment manufacturers include Elisra, Ferranti, Marconi Defence Systems, MBB MBB Men's Basketball
MBB Master Black Belt (Six Sigma)
MBB Medical Biochemistry and Biophysics (Karolinska Institutet, Stockholm, Sweden)
MBB Make Before Break , Perkin-Elmer and Thomson-CSF.
Direct linking of the RWR to countermeasures is illustrated by the case of the F-15, in which the Loral ALR-56C controls the Northrop ALQ-135B jammer and the Tracor ALE-45 dispenser.
Examples of fully integrated EW systems for tactical aircraft include the Marconi/Northrop Zeus for the Harrier GR5/7 and the Mirage 2000's ICMS ICMS Imposto Sobre Circulação de Mercadorias e Serviços (Brazilian excise tax)
ICMS International Centre for Mathematical Sciences

ICMS Integrated Customer Management System , in which Thomson-CSF cooperated with AMD-BA, ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine. See ESL. and Matra. Looking further to the future, INEWS is the integrated EW system for the USAF F-22/23 Advanced Tactical Fighter The Advanced Tactical Fighter (ATF) contract was a demonstration and validation program undertaken by the United States Air Force to develop a next-generation air superiority fighter to counter emerging worldwide threats, including development and proliferation of Soviet-era Su-27 , and will include countermeasures against not only radar but also IR and laser threats.
Airborne radar countermeasures traditionally take the form of stand-off and stand-in (escort) jamming, but many tactical aircraft can now carry (and in some cases house) their own defensive jamming equipment. Jamming may be performed by a transmitter that either swamps the enemy transmitter (i.e., noise or brute-force jamming) or produces misleading information (deception jamming), creating false targets or breaking radar tracking.
Enemy radars and radar-guided missiles may also be defeated by reflective clouds of chaff, i.e., aluminium foil strips, or aluminium-coated plastic strands or glass fibres. Chaff is normally carried in pylon-mounted launchers or "scabs" attached to the airframe or pylons, though in some cases the dispenser is mounted internally. For example, the AMX AMX American Motors Experimental
AMX Aeromexico Aerovias de Mexico (ICAO code)
AMX Air Mobility Express
AMX Amberjacks (FAO fish species code)
AMX Alabama Motor eXpress currently has four internal dispensers in the rear fuselage, and the MB-339C has dispensers in wing bays adjacent to the mainwheels. It is noteworthy that the MiG-29 has overwing dispensers firing upwards to prolong the dwell-time of the chaff cloud at a suitable height.
A comparatively new development is the "smart" threat-adaptive dispenser, which ejects a chaff or flare pattern tailored to the nature of the threat, as determined by the threat-warning system. One of the first such equipment is the Tracor ALE-45 for the F-15, which will be followed by the joint USAF/USN ALE-47.
The development of mini-jammers has largely been pioneered by the US Navy, using standard dispensers. These expendables are battery-operated, and may function either as noise jammers or deception repeaters. Current active expendables are exemplified by the Brunswick Corp. RFED RFED Radio Frequency Expendable Decoy (Radio Frequency Expendable Decoy) and the Sanders POET (Primed Oscillator oscillator
Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air Expendable Transponder), which entered service with the US Navy around 1980. In September 1987 the Navy awarded a full-scale development contract to Texas Instruments for a new generation designated GEN-X (Generic Electronic Expendable), providing broader band coverage than POET.
Although GEN-X will be relatively inexpensive, operating costs may in principle be reduced and effectiveness increased by the use of larger semi-expendables or towed decoys. These can be powered by and controlled from the parent aircraft and jettisoned at the end of the mission. Such decoys are being developed under the US Navy AAED AAED American Academy of Esthetic Dentistry
AAED Advanced Airborne Expendable Decoy (Advanced Airborne Expendable Decoy) programme. Whereas GEN-X has an overall dimension of only 15 cm, the AAED may be six times as long and correspondingly more capable. Work is also proceeding on a powered derivative that would fly ahead of the aircraft during an attack on a surface target.
In this context it may be noted that the Israelis used the Brunswick Corp. Samson drone as a decoy in the Lebanon in 1982, and that the US Navy has purchased an improved version. Samson is thought to use Luneberg lenses to give it a full-size radar signature, although a second variant is employed purely as a chaff-dispenser. It may also be noted that the USAF has a programme named Faitour fai·tour
An impostor; a deceiver.
[Middle English, from Anglo-Norman, from Latin factor, maker; see factor.] to develop a multispectral decoy to deal not only with radars but also with IR and EO threats.

Reports of this proposal also refer to the <<smart>> dispensing of IR flares, to such effect that a single flare will be sufficient to decoy an IR-homing missile.
The use of IR flares is based on the fact that a simple IR missile will switch lock from the aircraft to a close high-powered IR source. However, the effectiveness of such flares is limited by the number that can be carried and by the sophistication so·phis·ti·cate

If an aircraft may be subjected to IR missile attack at any stage of its flight, then (depending on the reliability of its threat warning system) a different type of IRCM IRCM Infrared Countermeasures
IRCM Institutul Roman de cercetari marine-Constanta may be required. Fortunately, most existing IR homers rely for their guidance on <<chopping>> the incoming IR energy. This is done by means of a rotating disc with specially-shaped transparent slots. The transmission thus becomes a series of pulses, the nature of which indicates target position relative to missile axis. If an IRCM equipment on the target can transmit pulses of a suitable frequency, then the missile will generate false guidance demands.
The leaders in this type of IRCM are Northrop, Loral and Sanders Associates. Northrop is believed to use electrical modulation to produce the pulses, and its production series began with the AAQ-4 used in the EB-66 in Vietnam. The AAQ-8 supersonic pod (also based on a vistal caesium caesium
cesium. source) was later fitted to some F-4s in the same war.
The Loral ALQ-123 IRCM pod is used on US Navy A-6s and A-7s, and reportedly on E1 A1 airliners. One of the first public showings of IRCM occurred at Le Bourget in 1983, when Sanders pods were fitted to the pylons of the B-747 Shuttle transporter. One of the most widely-used IRCM systems is the Sanders ALQ-144, which is fitted to many US Army helicopters and some British Army helicopters in Northern Ireland. Over 1000 have been produced. Current Northrop equipment is exemplified by the MIRTS (Modular IR Transmitting Set), used on some examples of the A300, B-707, B-747, DC-8, DC-10, Mirage Fl, Northrop F-5, Falcon 20, C-130 and BAe 125.
Although IRCM is currently effective against most IR homers, it can in principle be defeated by missiles with staring arrays of cells, just as flares can be defeated by the missile rejecting sources that also produce visible light.
On the subject of IR, mention may be made of missile launch warning systems that detect the flash of the weapon firing. This is presumably pre·sum·a·ble
That can be presumed or taken for granted; reasonable as a supposition: presumable causes of the disaster. the system used for the AAR-34 tail-warning system for the F-111 and the new AAR-44 for USAF C-130s, an equipment also produced by Cincinatti Electronics. The Sanders ALQ-156 uses pulse-Doppler radar to detect approaching missiles by measuring closure rates and other ballistic parameters, and activates counter-measures. Its first application is the US Army CH-47.
Turning to defence suppression, the concept of loitering Loitering (IPA pronunciation: ['lɔɪtəˌrɪŋ] is an intransitive verb meaning to stand idly, to stop numerous times, or to delay and procrastinate. anti-radar drones is gaining in popularity. The most important is probably the Northrop Tacit Rainbow (AGM-136A), which can be either ground- or air-launched. Significant ARM developments include the Matra STAR (Supersonic Tactical Anti-Radar) missile and the BAe ALARM, which scans for its target while descending on a parachute.
To counter such devices, some work is being done on equipment to decoy ARMs away from radars. The decoy is connected to the real radar, and emits sidelobes from a distance of several hundred meters. The principal US companies involved are LTV's Sierra Research division, ITT ITT Initial Teacher Training (UK)

* United States
The multiplicity of American EW equipments has become something of a national scandal, with over 60 systems now flying on USAF and Navy aircraft alone. In the following summary it is possible to mention only the principal companies involved, and some of their products.
The Brunswick Corporation is perhaps best-known in the electronic warfare context for its work on active expendables such as the RFED and its drone decoys, which are also built by Israel Military Industries. The original Samson decoy has been used operationally in the Middle East, and TALD TALD Tactical Air-Launched Decoy (Tactical Air-Launched Decoy) uses later technology and offers improved performance and payload. The TALD is used by the US Navy to protect its attack aircraft.
Cincinatti Electronics produces the AAR-34 and -44 tail warning systems. Eaton-AIL is responsible for the ALQ-161 defensive avionics system of the B-1B and the ALR-77 ESM system for the P-3C. General Instrument manufactures the ALR-66(VE) RWR recently ordered for RAF transports and tankers, and the ALR-87, which is made by the Dalmo Victor division. The company's Government Systems division is responsible for the ALR-80(V), which is described as an advanced version of the widely-used ALR-66(V), and the only RWR providing the user with complete and independent control of the system programming and maintenance.
Goodyear makes various cartridge dispensers, including the ALE-39 fitted to most US Navy aircraft. ITT Avionics has developed a series of jammers, notably the ALQ-129 used on Navy F-4s, A-7s and F-14s, and the ALQ-136 used to protect US Army helicopters and light aircraft against the ZSU-23-4.

Loral makes the ALR-56 RWR for the F-15, the ALQ-123 IRCM pod for Navy aircraft, the ALQ-157 IRCM equipment for Navy helicopters and the ALQ-178 Rapport warning, jammer and expendables system for some export F-16s. The company's ALR-56M advanced RWR for the F-16 is reportedly the USAF's biggest ever EW programme.
Lundy produces a series of cartridge dispensers, including the ALE-29A for Navy aircraft and the more recent ALE-43 and -44. Magnavox is responsible for the ALR-50 RWR fitted to a wide range of Navy aircraft.
Aside from its Tacit Rainbow anti-radar drone and series of IRCM equipment, Northrop's products include the ALQ-135 CW jammer for the F-15C, the ALQ-162 CW jammer for various Navy aircraft and the ALQ-171 conformal countermeasures system (CCS (1) (Common Channel Signaling) A communications system in which one channel is used for signaling and different channels are used for voice/data transmission. Signaling System 7 (SS7) is a CCS system, also known as CCS7. See SS7. ) for the F-5E. Perkin-Elmer products include the AVR-2 laser warning receiver.
Raytheon jamming systems include the ALQ-99 pod, up to five of which are used on the EA-6B. An onboard version is produced for the EF-111A. Raytheon's ALQ-142 is the ESM system for the SH-60, its information being data-linked to the SLQ-32 EW system of the parent ship. The company's ALQ-184 pod is effectively an upgrade of the Westinghouse ALQ-119 used on most USAF tactical aircraft. The ALQ-186(V) is a US Army jammer designed for testing air defence radar systems. Raytheon is also prime contractor for the Advanced Airborne Expendable Decoy (AAED) mentioned earlier in this report.

Its equipment includes the ALQ-126B reprogrammable jammer for US Navy aircraft, the ALQ-144, -146, and -147 IRCM series, the ALQ-149 communications jammer for the EA-6B and the ALQ-156 pulse-Doppler attack warning system. Sanders also makes the POET (Primed Oscillator Expendable Transponder) decoy, and is teamed with GE on the INEWS programme for the F-22/23.
Texas Instruments is probably the world leader in anti-radar missiles, with the AGM-88 HARM, and is prime contractor for the US Navy Generic Electronic Expendable (GEN-X) decoy. Tracor is the best-known name in dispensers, its range including the ALE-40 fitted to most USAF tactical aircraft, and the threat-adaptive ALE-45 for the F-15. Tracor is also experimenting with a towed decoy designated Big Boy.
Westinghouse has probably built more tactical jammers than any other company. It developed the ALQ-119, the first major USAF jammer pod, and is making the ALQ-131 (of which over 2000 have been ordered) for the F-16, F-111 and A-10. Westinghouse was responsible for the ALQ-153 tail warning system for the B-52, is teamed with ITT on the ALQ-165 ASPJ, and is teamed with TRW on the INEWS programme for the F-22/23. Whittaker Electronics is less well-known, but its ALQ-16(V) jammer is used on Royal Navy Lynxes and Sea Kings under the designation Yellow Veil.
In conclusion, it must be emphasised that the vast numbers of electronic warfare equipments now in service make it impractical to mention every type, and hence that the examples quoted are intended to be purely illustrative.
