Abstract :
The authors present the interferometric calibration of the X-SAR system on SRTM. From a height sensitivity analysis they identify key system parameters influencing the height reconstruction performance. Possible error sources in the radar instrument and the geometry determination are discussed. They outline the methods for calibrating the electronics and the geometric parameters and present first results of simulations
