一种W波段视频SAR微波系统

A W-band Video SAR Microwave System

鉴于视频合成孔径雷达(视频SAR)以类似视频播放的方式再现场景信息能极大提升战场态势感知能力,设计了一种适用于小型无人机平台的W波段视频SAR微波系统.该系统采用双反射面卡塞格伦天线、一体化多层叠拼超外差模拟收发链路和高精度内外环双力矩弧齿天线伺服控制,具有集成度高、体积小、成本低的特点.测试结果表明,该系统的主要性能指标能够满足雷达工作要求.

Considering video synthetic aperture radar(SAR)reproduces scene information in a manner similar to video playback,which can greatly improves battlefield situational perception,this paper designs a W-band video SAR microwave system for small unmanned aerial vehicle(UAV)platforms.The system uses dual reflector Cassegrain antenna,all-in-one multi-layer stacking superheterodyne analog transceiver link and high precision inner and outer ring double-torque arc tooth antenna servo control,which has the characteristics of high integration,small size and low cost.The experimental results show that the main performance indicators of the system can meet the requirements of radar operation.
