摘　　要：本文讨论了软件化电子战侦察接收机多信号处理问题。使用多相滤波的宽带数字化接收设计技术,可以提高接收机的实时处理能力,提高全概率截获能力。本文讨论基于多相滤波的信道化接收机的基本原理及实现方案,给出了基于FPGA的数字信道化接收机的实现方法,实验结果证明了该方法是有效的。This paper discussed the problem of how to realize multi-signal processing on software EW reconnaissance Receiver. Based on the technogy of wideband digitized receiver with polyphase filter, to enhance the real-time processing ability of receiver and to improve the entire probability interception ability of receiver. This paper discusses basic principle and the realization conceptual of channelized receiver based on plolyphase filters, and the realization method of channelized receiver based on the FPGA is given. The method is validated by the test results.
