Abstract

Abstract:

Based on the characteristics of the ScanSAR mode, the mechanisms of scalloping effect are analyzed. A detailed description of TOPSAR in terms of data acquisition principle, signal characteristics, and processing algorithm is presented. Simulations for the point targets using ScanSAR and TOPSAR are implemented and the results show that TOPSAR has solved the problem of periodical modulation of the amplitude in ScanSAR.

Key words: SPECtral analysis (SPECAN), TOPS, ScanSAR, BAS, scalloping
