摘　　要：提出了一种基于多相滤波器的信道化数字检波方法,该方法可以满足雷达脉冲检波的实时性和大带宽的要求,抽取运算在滤波之前,运算量小,结构高效,易于在可编程大规模集成电路上实现。A method of channeiized digital demodulation based on poly-phase filter is presented. This method satisfies the requirement of real time processing and bandwidth in demodulation for radar pulse signals. The efficient architecture is built by decimating the data prior to filtering,so the digital signal processing can be realized easily in large scale integrated circuits.
