摘　　要：微型化、模块化、数字化是现代雷达接收机的发展趋势。该文提出了一种新的宽带低中频雷达接收机拓扑结构,它不仅结构简单,可以全集成化,同时又能获得较好性能。该文还给出了一部应用于L波段的宽带低中频雷达接收机的设计实例。Micromation, modularization and digitization are the trends of modern radar receivers. This paper presents a novel wideband low-IF receiver topologies suitable for fully integration. Its architecture is very simple, and can attain very good performance. Also a design example of wideband low-IF radar receiver application in L-band radar is put forth.
