Airborne 1177

This ruggedized, air cooled, minitiaturized airborne 1 Bit DRFM has a 500+ MHz instantaneous bandwidth with >6 dBc worst case spurious suppression across the entire band with typical spurs >10dBc. This airborne model is fully self-contained with up to 16 deception programs. Through the user-friendly interface, you can easily define the ECM techniques for Pipeline, Stretched Pulse, including synthetic CW (SP) and Multiple False Target (MFT) Modes. Development of this replacement for the 1030 DRFM in a smaller ruggedized package with significant additional capablilty was contracted by the U.S. Navy.
