摘要
数字信道化接收机具有瞬时频带宽、动态范围大、能实现超宽带侦察的特点,能较好地满足现代电子战接收机的要求。首先介绍了数字信道化接收机的基本原理,在此基础上,重点分析了数字信道化接收机在信道化过程中的研究热点和难点,并简述了信道化接收机技术的发展趋势。
A digital channelized receiver has the characteristics of wide instantaneous frequency bandwidth, large dynamic range and realizing ultra wideband reconnaissance. It can meet the requirements of modern electronic warfare better. Firstly the basic principle of digital channelized receiver is introduced. On this basis, the hotspots and difficulties in the channelization of the digital channelized receiver are analyzed. Finally the de- velopment trend of the technology of the channelized receiver is summarized.
