OSPREY'S RADAR-WARNING SYSTEM TESTED ANECHOIC CHAMBER UTILIZED AT EDWARDS.Byline: Daily News EDWARDS AIR FORCE BASE Edwards Air Force Base, U.S. military installation, 301,000 acres (121,805 hectares), S Calif., NE of Lancaster; est. 1933. It is one of the largest air force bases in the United States and has the world's longest runway. - Testing of the Air Force's CV-22 tilt-rotor aircraft tilt-rotor aircraft: see vertical takeoff and landing aircraft. has been completed in the base's anechoic chamber Noun 1. anechoic chamber - a chamber having very little reverberation room - an area within a building enclosed by walls and floor and ceiling; "the rooms were very small but they had a nice view" , designed to keep radio or radar signals from bouncing around inside. Testers examined the radar-warning receiver and electronic countermeasures Noun 1. electronic countermeasures - electronic warfare undertaken to prevent or reduce an enemy's effective use of the electromagnetic spectrum ECM on the CV-22, also known as the Osprey osprey (ŏs`prē), common name for a bird of prey related to the hawk and the New World vulture and found near water in most parts of the world. . ``This last round of tests has basically verified that a lot of our design changes are giving us the type of performance that we're looking for Looking for In the context of general equities, this describing a buy interest in which a dealer is asked to offer stock, often involving a capital commitment. Antithesis of in touch with. ,'' said Maj. Greg Weber, the government's CV-22 flight test director at Edwards. The test team started with antenna pattern measurements in the chamber. ``As is always the case, whenever you install antennas on the airplane and begin testing them, there are things that don't exactly work the way some models say they would,'' said Weber. After adjustments to the antennas were made, the test team moved on to more than eight weeks of electronic warfare testing. According to Rex Wade, Bell-Boeing's electronic warfare lead test engineer, some factors can't be effectively tested during flight, such as the interaction between the radar-warning receiver and electronic countermeasures and the aircraft's multimode radar system. ``Part of our testing is designed to find not only how well the system works, but also seeing how well it works in conjunction with other aircraft systems,'' said Wade. The next step will be for Bell-Boeing to analyze the data from the testing and make recommendations to the CV-22 program office. Once analysis is complete, the test team will take the airplane and fly it on the open-air ranges for testing.
