Abstract
A method to estimate baseline parameters for SAR interferometry is described in the paper. The proposed method uses three interferograms by three observations. This method is applied to ERS-1 SAR data. The result shows that baseline parameters are estimated with residual phase difference RMS error of less than 20° (about one-twentieth of a cycle), while initial phase difference error calculated by using orbit information is more than 2100° (several cycles)
