Abstract:

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.

Key words: radar interference suppression, blind signal separation, anti-jamming, convolutive mixture, fourth-order cumulant, joint block diagonalization
