摘要
针对国内外越来越热的利用重复轨道合成孔径雷达干涉测量(INSAR)技术来监测形变量较小或形变范围较小的地表形变的应用需求,本文针对影响重轨INSAR地表微量形变监测精度的多个误差因素进行了分析,并对在利用INSAR监测地表微量形变应用中,如何削弱这些误差因素的影响给出了相应的方法。
At present, application of interferometric synthetic aperture radar （INSAR） to monitoring surface small deformation or small area deformation is used more and more. According to this satuation, this paper analyzed these error effects in monitoring the surface small deformation with INSAR on heavy rail. At last, some methods to weaken these error＇s effects were presented.
