B-1 Pioneers Airborne Phased Array
Baltimore—The Westinghouse AN/APQ-164 multifunction radar for the USAF/ Rockwell B-1B, pioneering the use of a phased-array antenna for airborne applications, is scheduled to start flight tests this summer on a B-1 A. Phased-array technology enables a single antenna to provide a very high resolution ground-mapping beam for weapons delivery and navigation, which is time-interleaved with a different, optimally shaped beam for terrain following and avoidance, eliminating the need for multiple antennas.
