数字阵列雷达系统

Study of the digital array radar system

文章介绍了收发全数字波束形成的全数字化相控阵雷达(DAR)的原理、系统组成及目标显示。对其中的主要功能模块数字阵列模块(DAM)、数字T/R组件及数据传输系统进行了详细地分析,通过512单元的完整试验系统,得出数字阵列雷达同时完成观察和跟踪多目标终端显示图。

This paper introduces the principle, system composition and target indication of a fully digitized phased array radar in which digital beam forming techniques are used in receiving and transmitting. The main function modules are analyzed in detail, including the digital array module（DAM）, the digital transmitting/receiving module and the data transmission system. Finally,the terminal demonstration chart of searching and tracking multiple targets is obtained through the complete experimental system of 512 units in digital array radar.
