| 摘 要： | 由频率调制导出的 P3、P4多相码是一类常见的脉冲压缩信号 ,已提出的几种旁瓣抑制技术可用于降低这类脉压信号的压缩输出旁瓣。本文主要研究在使用这几种旁瓣抑制技术时 ,多普勒频移对 P3、P4多相码压缩输出性能的影响 ,包括多普勒频移对输出峰值旁瓣电平 (PSL )以及信噪比 (SNR)损失的影响。文中给出了计算机仿真结果。

| Abstract: | Polyphase codes derived from linear-frequency-modulation, such as P3 ,P4 codes , are a common class of pulse compression waveforms. Several side-lobe reduction techniques have been proposed which can be used for those codes.This paper shows and compares the Doppler response performances of P3, P4 codes when several different side-lobe reduction techniques are employed, including the output peak side-lobe level(PSL) and the signal-to-noise ratio(SNR) loss. Some simulation results are shown. |

| Keywords: | polyphase code pulse compression side-lobe reduction Doppler shift |
