| Abstract: | A method of channelized 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. |
