Ultrashort Wave FH Signal Digital Channelizing Detection Research

As one of the most useful method in the field of EW frequency detection , wideband digital channelized receiver system has almost covered all virtues of EW receiver . This dissertation focuses on researching the key technology of wideband digital channelized receiver . The outline of the dissertation is as follows.Firstly, two key-points of wideband digital channelized receiver structure are studied after referring to research papers. And then two kinds of postposition processors , which are placed after channelized receiver , have been comparied in chapter 4. After comparison , phase comparators receiver, with its superior performances over high frequency resolution, has been drawn wide attentions in dealing with signal after channelized. Finally wideband digital channelized phase comparators receiver implementation with FPGA is described in this dissertation and each of its composition has been studied to advance performance and enhance feasibility.
