Aeroflex Announces New Radar Stability Test System with Superior Accuracy; New Measurement Technique Gives PN9002 Superior Accuracy at a Fraction of the Cost of In-House Systems.Business Editors/High-Tech Writers PLAINVIEW, N.Y.--(BUSINESS WIRE)--April 7, 2003 Aeroflex Incorporated (Nasdaq:ARXX) today announced the PN9002, a new pulse-to-pulse radar stability test system designed to improve the accuracy of ground-based radar design for example, while significantly reducing the cost of radar testing. The PN9002 system enables measurements of amplitude amplitude (ăm`plĭt  d'), in physics, maximum displacement from a zero value or rest position. and phase
stability of radar pulses with a dynamic range superior to any
commercial or custom system. To achieve the accuracy necessary for
designing today's radar systems, most radar system designers rely
upon test systems that are built in-house In-houseIn the context of general equities, keeping an activity within the firm. For example, rather than go to the marketplace and sell a security for a client to anyone, an attempt is made to find a buyer to complete the transaction with the firm. . The Aeroflex PN9002 eliminates the need for radar designers to spend time building test systems that can cost their company up to $1 million to develop. By using the PN9002's superior dynamic range and in-pulse measurement technique, engineers can dramatically improve their radar design -- it will detect smaller targets at farther distances, with smaller return echoing. "We have developed the PN9002 test system to enable designers and manufacturers to perform high-accuracy radar stability testing Stability testing can refer to:
About the PN9002 Pulse-to-Pulse Radar Stability Test Systems The PN9002 is a unique test system for the design and manufacturing of radar systems. Fast, compact and fully automated au·to·mate v. au·to·mat·ed, au·to·mat·ing, au·to·mates v.tr. 1. To convert to automatic operation: automate a factory. 2. , the PN9002 is a stand-alone system, ideal for radar stability measurements. It integrates hardware and software to test a two-ports module for amplitude and phase stability. The PN9002 acts as a "micro-radar" providing pulsed signals to the unit under test (UUT Uut, symbol for the element ununtrium. ) and analyzing the received pulses. The system covers 400 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. to 18 GHz in a scaleable configuration that can be extended for future needs. The PN9002 guarantees the lowest noise floor available in the market today. The dynamic range reaches an unprecedented -79dBc in stability integration over the bandwidth of the equivalent receiver. The Need for More Accurate Testing Grows with Adoption of Phase-Array Antennas Before the PN9002 pulse-to-pulse stability measurement system, amplitude and phase stability measurements of radar signals were only accomplished by a system of averaging the radar pulses. Because of the wide time frame between the "on" and "off" part of the pulse, the "off" part of the pulse being sampled added significant noise to the measurement, creating a less accurate measurement. The new PN9002 measurement technique does the analysis of the radar pulse inside each pulse during the "on" part of the pulse. By not sampling the "off" part of the pulse, the added noise is eliminated. Sampling inside each burst and pulse, the PN9002 provides a real-time amplitude modulation/phase modulation modulation, in communications modulation, in communications, process in which some characteristic of a wave (the carrier wave) is made to vary in accordance with an information-bearing signal wave (the modulating wave); demodulation is the process by which (AM/PM AM/PM Amplitude Modulation/Phase Modulation AM/PM Ante Meridian/Post Meridian ) measurement ideal for TWT TWT The Washington Times TWT Traveling Wave Tube TWT Teaching with Technology TWT Time Will Tell (Robert Cray song) TWT Tri-Wizard Tournament (Harry Potter event) TWT Third Wave Technologies, Inc. amplifiers and transmitter/receiver (T/R T/R Transceiver T/R Transmit/Receive T/R Transmitter/Receiver (also seen as TR) T/R Thanks and regards T/R Tail Rotor (helicopter) T/R Tip/Ring T/R Trust Receipt T/R Transmission/Reflection ) module testing. The PN9002 provides an accurate measurement that allows the radar engineer to design tighter specifications. The exceptional accuracy results in a radar system that detects targets that are farther away or smaller. This measurement is critical to improving any radar system. However, with the rapid adoption of phase-array antennas, the need for this measurement will become even more necessary and widespread very soon. While conventional radar systems require the testing of only one amplifier, a single phase-array antenna incorporates up to 3,000 modules that need to be tested, dramatically increasing the amount of testing. With the PN9002's automated capabilities, high-volume testing is fast, providing an immediate solution to testing large volumes of amplifiers to tight specifications.
