摘要
讨论了脉压信号的频谱特性 ,对多种波形采用改进的谱修正技术进行旁瓣抑制处理 ,在信号时带积较小采样率较低的情况下 ,模拟分析及实验结果均证明此方法效果明显 ,使主副比改善约 3dB～ 6dB。
This paper analyses the spectrum properties of various pulse compression signals and modifies the filter spectrum to reduce the range sidelobe.Under Nyquist sampling rate and small TB conditions,it is proved to be effective by computer simulation and experiments of a practical system.The RMS of compression output is improved about 3dB～6dB.
