摘要
文中介绍了机载毫米波InSAR地形测绘的原理与方法,并通过试验研究,分析了机载毫米波InSAR技术测制的3D(DEM、DOM、DLG)成果的平面精度和高程精度。讨论了影响DEM高程精度和DLG平面精度的因素。试验表明采用我国自主研发的机载毫米波InSAR系统测制的3D成果,满足1∶5000国家规范的精度要求。
The paper introduces the principle and method of topographic mapping with airborne millimeter wave InSAR,and based on experiment,analyzes the plane precision and elevation precision of 3D（ DEM,DOM,DLG）with airborne millimeter wave InSAR. And then it discusses the factors determining the accuracy of DEM height and DLG plane. Experimental results shows the 3D made by the airborne millimeter wave InSAR,which is researched and developed independently by China,meets the requirements of 1： 5000 precision of the national code.
