CRInSAR大气校正模型比较与分析

Comparison and Analysis of CRInSAR Atmospheric Correction Model

人工角反射器辅助雷达干涉测量(CRInSAR)中,电磁波信号受各种因素的影响,其中大气能够引起信号延迟和传播路径弯曲,在此先对已有大气中对流层校正模型进行比较,然后对基于GPS数据和气象观测数据的大气改正方法进行试验研究,证明大气校正模型对雷达干涉测量的影响和消除的有效性。

Corner Reflector Interferometric Synthetic Aperture Radar（CRInSAR）,electromagnetic wave signal is affected by various factors.The atmosphere can cause signal delay and propagation path curve.First,the available atmospheric correction models were compared.Then,atmospheric correction methods based on GPS data and meteorological observation data were studied,the influence of atmospheric model to the radar interferometry and effective elimination were proved.
