摘　　要：讨论双向加权超低副瓣脉冲压缩算法,针对其存在的缺点在谱修正技术基础上进行算法改进。试验了线性调频信号和非线性调频信号在改进算法中旁瓣抑制的效果,通过Matlab仿真结果表明,改进的双向加权脉压方法对调频信号具有很好的旁瓣抑制能力。The ultralow side-lobe pulse compression algorithm with bidirectional weighting is discussed,and is improved on the basis of spectrum correction technique. The side-lobe suppression effect of LFM signal and NLFM signal in the improved algorithm was tested. The results of Matlab simulation show that the improved bidirectionally-weighted pulse compression method has high side-lobe suppression ability for the frequency-modulated signal.
