Airborne Parasitic Bistatic Radar System

Phase II.5 of the Airborne Parasitic Bistatic Radar (APBR) program will demonstrate successful operation of the APBR system on multiple airborne platforms in varying clutter environments. The objective of the Airborne Parasitic Bistatic Radar (APBR) program is to develop a compact airborne PC-based passive surveillance system that utilizes non-cooperative radar transmissions to generate a bistatic radar picture. The APBR"software radar"implementation provides maximum flexibility, while minimizing cost and hardware size, weight and power (SWaP). The designed surveillance system accepts two Intermediate Frequency (IF) feeds from available host platform antenna/RF receiver assets, digitizes the IF signals and provides digital signal/data processing of the radar data. Since the APBR processing system will, most likely, be used on existing platforms with existing antennas and front-end radio frequency (RF) processing, the APBR is designed to input data at the IF level, thus making it applicable to a wide variety of host applications.
