摘要
宽带数字信道化接收机具有覆盖频段宽、灵敏度高、动态范围宽、截获概率高以及实时处理能力强等特点,是目前侦察接收机中较好的解决方案。论述了一种基于多相滤波的宽带数字信道化接收机结构,并通过FPGA布局布线后仿真验证其有效性及可实现性。
A wideband digital channelized receiver has the characteristics of wide coverage frequency range, high sensitivity, large dynamic range, high interception probability and strong real-time processing ability,is a satisfied solution project in current reconnaissance receivers. This paper discusses a structure of wideband digital channelized receiver based on polyphase filtering technology, and validates the validity and realizability of the design through the simulation after placing and routing in field programmable gate array （FPGA）.
