Blind signal separation (BSS) has been used to realize the radar anti-jamming. A new algorithm of radar interference suppression based on convolutive BSS is proposed and the radar performance is improved. Through the joint block diagonalizaton of fourth-order cumulant in the time domain the separation of the radar signals and the jamming is realized. Simulation results show that the new method has better performance of separation.
