Abstract :
In this paper different maximum a posteriori estimation approaches for interferometric parameter calibration are analysed. From this analysis a method for accurate estimation of the crucial parameters will be derived. First simulation results with regard to the Shuttle Radar Topography Mission (SRTM) will be presented
