Abstract

This paper present a novel technique for the ‘reduction of the side-lobes in the pulse compression (PC)’ for the radar systems. This pulse compression increases the range resolution and signal to noise ratio. The peak sidelobe ratio and signal noise reduction loss are computed using P4 polyphase codes. This result is compared with various weighting techniques applied on the output of Woo filter in order to suppress the side lobes. This proposed PC technique is implemented by shifting the input P4 polyphase codes and multiplied it with reference signal. This technique produces certain improvement in Peak Sidelobe Ratio and Signal Noise Reduction Loss(SNR Loss).
