摘　　要：在现代电子对抗中,数字信道化技术应用越来越广泛。基于数字信道化技术的宽带数字接收机具有带宽大、体积小、稳定性好的特点。针对传统被动雷达导引头接收机不能处理同时到达多信号问题,提出将数字信道化技术应用于被动雷达导引头接收机,以实现大瞬时带宽和同时到达多信号处理的性能。对数字信道化技术的基本原理进行了介绍和分析,并且对数字信道化技术在宽带被动雷达导引头应用中的主要指标设计进行了分析。Digital channelize technology has been widely used in modern electronic countermeasures.The broadband digital receiver based on digital channelize technology has the excellence of broadband,compact volume and good stability.Traditional PRS receiver can’t process simultaneously impinging signals.To deal with this problem,digital channelize technology is proposed to apply in PRS receiver.The principle of digital channelize technology is introduced and the relative factors of the algorithm are analyzed,and the main indicators of digital channelize technology which used in broadband PRS are analyzed.
