APPLICATION OF TIME-DOMAIN NUMERICAL SIMULATION FOR MULTI-APERTURE ALONG-TRACK INTERFEROMETRIC SAR

Abstract

TMulti-aperture along-track interferometric (MA-ATI) SAR was proposed by Ouchi et al. to estimate velocity vector. On the other hand, a numerical simulation in the time domain was developed to calculate time-series SAR raw signal by Yoshida et al. he simulation is assumed as an airborne scale and the SAR is L-band. To calculate microwave backscattering, physical optics approximation was used. In this paper, we show an application of the time-domain simulation for MA-ATI SAR. Along-track interferometry with multi-look processing was applied, and then the simulation was performed for a moving target to detect its velocity. It results in validation of MA-ATI SAR. et al. he simulation is assumed as an airborne scale and the SAR is L-band. To calculate microwave backscattering, physical optics approximation was used.
