Abstract Phased array radar combined with wideband technique is the development trend in radar, while technology of restraining wideband interference must be resolved in wideband phased array radar. A new wideband transmitting beamforming method is presented in this paper which uses LFM signal. The algorithm produces optimal weight by combining wideband with narrowband weight on the premise of accurate DOA estimation. The method can ensure high distance resolution of the signal and form pattern null in the direction of the interference. Simulation results demonstrate the effectiveness of the method.
