According to the requirements of radar and electronic warfare(EW) integrated system,this paper designs a kind of high efficiency and high velocity 32-channel real-time multiphase channelized broadband digital receiver based on the ISE 10.1 tool development platform of Xilinx.For eliminating the reception dead zone due to the extraction,this paper uses the structure of 3 dB overlapping and overlapping 50% between adjacent channels.All the design schemes are described by the VHDL language.The ModelSim tool software is used in large-scale programmable logic devices XC5VSX95T of Xilinx company to realize the system logic synthesis and time sequence simulation.The computer simulation verifies the correctness and effectiveness of the method,the output data rate of the structure is stable,and the feasibility of its hardware is good.
