Design of Digital EW Receiver Based on Software Radio Conception

Base on software radio conception,we present a new FPGA-based method of designing digital EW receiver.In the system design,the top-down method were used,first analyze and design the sub-module,then instantiate sub-module in the top design file.And implement it in practical project.Results in the project show that the method has advantages of real-time performance and high precision in pulse parameter measurement.
