| Abstract: | A digital channelized receiver has the characteristics of wide instantaneous frequency bandwidth, large dynamic range and realizing ultra wideband reconnaissance. It can meet the requirements of modern electronic warfare better. Firstly the basic principle of digital channelized receiver is introduced. On this basis, the hotspots and difficulties in the channelization of the digital channelized receiver are analyzed. Finally the de- velopment trend of the technology of the channelized receiver is summarized. |
