摘要：
A method for estimating the terrain height of interferometric synthetic aperture radar InSAR is proposed. Errors in height estimation due to the curvature of the Earth's surface are analysed and simulated. By using L band SIR-C data for the 'Three-Goge' area in China, the terrain height is obtained by employing the method. A method for estimating the parameters of the baseline is also presented. Simulations show that, under certain conditions, good results can be obtained.
