摘要
基于重轨干涉相干测量的基本原理 ,利用ERS 1/ 2重轨干涉雷达数据 ,对大部分地表有、无积雪覆盖时的地表的相干特性进行了分析 ,并在此基础上 ,利用地物的相干特性和振幅强度信息 。
Based on the theory of coherence of repeat pass SAR interferometry and by means of ERS 1/2 repeat pass SAR interferometry data, coherence signatures of land cover with and without covered by a large of snow are analysied Furthermore, land cover without covered by a large of snow is identified and classified by using coherence and amplitude information of ERS 1/2 repeat pass SAR interferometric data
