SAR interferometry-novelty in real scenario

A lot of efforts have been put in so far in the InSAR signal processing to develop easier yet accurate methods of generating topographic maps and other products. In order to facilitate better understanding and application of the SAR interferometry, however, there still remain short comings while taking into account certain important factors during various steps. In this paper efforts have been made to encompass all areas in the conventional InSAR signal processing which possess an appropriate reference of relationship with the processing in the real scenario. Methods and relationships have been developed to enable retrieve the accurate results as much as possible. The relevant processing steps have been identified and recommendations have been made to bridge the gaps between the novel and the real InSAR signal processing. The necessary steps involved in processing the received data to the geometrically compensated digital models have been explained in an easy and comprehensible way.
