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。
The spectral characteristics of pulse pressure signals are discussed. The sidelobe suppression is applied to a variety of waveforms using the improved spectral correction technique. Simulations and experimental results demonstrate the effectiveness of this method Obviously, so that the main and auxiliary ratio improved about 3dB ~ 6dB.
