Abstract
An algorithm based on time-frequency decoupling BSS ( TFD-BSS ) is proposed to solve the problem of single-channel deception jamming suppression of LFM fuze. First, the method transforms the signal of time-frequency mixed LFM fuze into two difference frequencies,and then filters out the deception difference frequency signal using the technique of adaptive filtering,and constructs a virtual channel by the second stretch transformation which can transform the jamming difference frequency into deception jamming signal,thus the underdetermined problem can be converted to well-posed BSS to take advantage of it to re-alize the separation and suppression of deception jamming. The experiment results indicate that the mixed signals can be separated successfully when the delay difference is more than 5 ns,and this method can pro-vide reference for deception jamming resistance of the fuze,and it is also the theory extension of single-channel BSS.关键词
