Abstract:

This paper presents a new jam nulling scheme for airborne synthetic aperture radar using digital beam forming. This scheme adaptively adjusts the weight vector of each receiving channel to form the beam pattern which receives the radar echo without distortion and nulls the interference. An optimized sector nulling technique is introduced for reducing the times of weight adjusting. Further more, the performance analysis of this scheme is given. Simulation results show its efficiency and feasibility.

Key words: SAR, digital beam forming, ECCM techniques, STAP, sector nulling
