基于GPS和DirectDraw的SAR运动轨迹记录技术研究

本文介绍了合成孔径雷达（SAR）的运动轨迹记录技术,该技术主要应用于合成孔径雷达成像处理器和地面处理系统中,以实现雷达图像采集过程中运动轨迹的记录并通过DirectDraw技术将雷达运动轨迹标注在地图中。研究主要内容包括雷达经纬度信息的获取,以及通过经纬度信息将雷达在地图上进行定位。雷达经纬度信息的获取是通过GPS模块来实现的,将雷达在地图上进行标定是通过MFC的DirectDraw来实现的。最终该项技术已经成功的应用于雷达的地面处理系统中。

Research on SAR moving path recording technology based on GPS and DirectDraw

This paper introduces SAR moving path recording technology,which is applied in SAR imaging processor and ground data handling system,to realize the moving path recording during the radar image acquisition and mark the SAR moving path on the map through the technology of directdraw.The main content of the research is capturing information of radar latitude and longitude as well as positioning radar in the map by using the latitude and longitude information. The latitude and longitude information of radar is acquired by using a GPS module.The positioning of the radar in the map is implemented by using directdraw of MFC.This technology is successfully applied in the SAR ground data handling system.
