Anti-jamming Performance Of Pulse Compression Radar Signal

Theory and emulation data are offered for searching after the best conjamming Radar signal form and for interfering advanced Radar signal, in this paper, through emulation and analysis of several signal on the different interference. The main conclusions and original results are summarized as follows. LFM and BC and their compounded signal, LFM-BC and BC inter-modeling are studied by the numbers in this paper. The course of pulse compression process is analyzed and the results of emulation are offered. Through modeling, SNR of input and output and RMS of output are computed from the point of view of signal theory, performance of several kind of advanced Radar signal is analyzed and the results are validated by soft emulation. The results of computing and emulating indicate that noise jamming and pulse jamming are invalidated for LFM, but shift-frequenfy jamming and range pull off jamming are valid. The performance of con-jamming of noise and pulse is better, for BC. Obviously, noise jamming is more and more with intensity. Part code copied jamming and distance deceiving jamming is valid. LFM-BC is compounded LFM and BC, so it has their performance. First, it has more performance of anti-noise-jamming and anti-pulse-jamming than LFM and BC. Second, shift-jamming and range pull off jamming are also valid. Difference lies in LFM-BC signal can withstand the LFM-jamming and BC-jamming. BC inter-modeling signal is a discrete style of BC signal, on the one hand, the signal has better anti-jamming performance than BC signal; on the other hand, it has worse anti-jamming performance than LFM-BC signal.
