中文摘要：
宽带数字信道化接收机以其高性能在电子战和无线电通信中有着重要的运用.本文基于复杂电磁环境下电子战的运用需求,分析了信道化接收机系统的发展现状和趋势;研究了目前的数字信道化接收机技术的主要系统结构及其发展趋势;重点分析了信道化接收机技术的发展历程和发展趋势.根据目前的信道化接收机系统和数字信道化接收机技术的现状可以看出,数字信道化接收机发展的一个趋势是：宽带数字化（大量子信道）和非均匀信道化接收机及动态信道化接收机.
英文摘要：
Wideband digital channelized receivers have an important application in Electronic Warfare（EW）and wireless communication,especially in Electronic Intelligence systems（ELINT）and Radar Warning Receiver（RWR）systems.This paper introduces the channelized receiver systems and the structures of the channelized technique.And base on the analysis of the development history of the channelized Receivers,we can see that the channelized Receivers system trend towards wideband digital and the digital channelized technique trend towards nouniform channelized to make channelized Receivers more suitable to the modern EW.
