Abstract: This paper presents a suppression method based on Blind Signal Separation (BSS) to counter deception jamming in the single channel. First, the received signal is cut into 3 sections. Next, the mixed one is separated into two parts by the Joint Approximate Diagonalization of Eigenmatrices (JADE) BSS technology. Then, those 4 parts are combined with each other to form two complete signals, namely, echo and deception jamming. Finally, the target and deception jamming are identified by the character of phase quantization. The experiments validate the effectiveness of the proposed algorithm. This approach has good performance under high SNR. When SNR15 dB, the similarity coefficient of target echo is larger than 85%. Under the condition of 4 quantization bits, the probability of identification is almost close to 1 and the measurement error of target delay is below 0.3 s.
