REDUCTION METHOD FOR SIDE-LOBE LEVEL OF LFM SIGNAL

摘要

FIELD: electricity. ^ SUBSTANCE: distinction of the claimed method from known ones is that weighted amplitude-frequency window is formed directly by type of LFM signal autocorrelation function from dependency where |smain_lobe(j, f)| is a module of main lobe complex range for autocorrelation function of initial LFM signal; |SLFM signal(j,f)| is a module for complex range of initial LFM signal at that before compression of LFM signal its phase spectrum is corrected. ^ EFFECT: maximum suppression of side lobe level with unchanged width of LFM signal for main lobe and increase of signal-noise ratio in result. ^ 9 dwg
