摘要
本文研究了基于频带分割与多通道综合的超宽带雷达脉冲压缩方法，并对该方法进行了详细的性能分析．它有效地解决了超宽带雷达带宽高达几千兆赫的信号没法直接A／D转换的难题．同已有方法相比，它不仅适用于LFM信号，也适用于非线性调制频信号．
This paper studies a multi-channel synthesis pulse compression method of an UWB radar based on intersection of frequency spectrum,and analyzes its performance in detail. This method effectively solves the problem of direct A/D conversion of the UWB radar signals up to several GHz.Compared with the existing methods, it can be applied to not only LFM signals but also non-inear frequency modulation signals.
