Own to its high performance,the Channelized Digital Receiver plays a great role in EW(Electronic Warfare) and wireless communication. This article gives details about the design of a dynamically and heterogeneously channelized digital receiver. The hardware architecture of the receiver,the firmware design and the ifnal test results are described. CPCI architecture is used in the design. Due to the technique use of RF sampling,dynamically and heterogeneously channelization and Digital Down Convert,the receiver can intelligently deal with many kinds of radar signals.
