摘　　要：介绍了机载雷达影像的成像特点以及干涉雷达生产DEM的方法,对由于自然环境困难、气候条件恶劣而造成的光学影像难以实现的区域采用雷达干涉测量技术获取地表高程信息的方法进行了试验生产,并检测了利用机载雷达影像干涉测量方法生产DEM的精度情况,最后分析了此方法的效率和适用性等问题。This paper introduces the imaging characteristics of airborne SAR and the methodof DEM production by InSAR, does the production experiments of obtaining earth＇s surface elevation information by using InSAR inlerferometry technology in the areas with diffieuh natural enviro,lment and bad climale condition where it is difficult to be realized by the optical images, and checks the accuracy of I）EM produced by lhe airborne lnSAR images. At lasl, it analyzes the situations such as efficiency, applicabilily and so on of this method.
