摘　　要：采用多波束开关馈线与相控波束扫描相结合的技术实现了一种低成本毫米波二维电扫描有源相控阵雷达。该雷达主要包含电扫的关键组件Rotman透镜与多端口TR组件,配以高性能的模块化数字信号处理机。试验结果表明,该雷达能实现动目标检测与跟踪、前斜视调频步进SAR成像与扇扫成像。This paper introduces a low cost millimeter- wave（MMW） active phased army radar, which can perform two - dimensional electronic beam scanning（phase controlled in azimuth while multi - beam ports switched in elevation）. This radar is mainly composed of Rotman lens stack, multi - port T/R modules, and high - pow- ered digital signal processor. Test result shows the radar can realize moving target detecting and tracking, squint - looking FM - stepped SAR and DBS（Doppler Beam Sharpening） imaging.
