基于FPGA的雷达脉冲预分选器设计

Design of Radar Pulse Signal Pre-sorting Based on FPGA

现代电子战环境复杂,信号密度大,所以对信号的实时分选很重要。这里,提出一种基于关联比较器的雷达信号分选方法,在实现多参数分选的同时,也保证了实时性。详细阐述了在Virtex 4系列FPGA上实现基于内容可寻存储器(CAM)的关联比较器的途径。

Real-time sorting to signal is very important in modern battlefield because electronic warfare （EM） environment is complicated and signal density is very high. The method of radar signal sorting based on coherent processors is discussed. The realization of the coherent processor based on content addressable memory （CAM） by a Virtex4 series FPGA is discussed in detail.
