Side Lobe Suppression of LFM-BC Signal Based on Sliding Window
Yin Hong-pei · Shipboard Electronic Warfare · 2004
An form of radar pulse-compression signal which composed of linear frequency modulation and bi-phase coding is studied in this paper.Expression of this kind of signal is given.This paper presents 5-point sliding window LFM side lobe suppression filter,and aiming at the requirement of double weighting in side lobe suppression of LFM-BC signal,this paper designes a kind of side lobe suppression weighting net based on 5-point sliding window.By means of simulating test,it is proved that this new method could complete the side lobe suppression of LFM-BC signal and the complexity of designing weighting filter net is depressed.
