Interferometric sar imagery of a monochromatic ocean wave in the presence of the real aperture radar modulation

Research output: Contribution to journalArticlepeer-review

Abstract

The model which allows one to simulate the Synthetic Aperture Radar (SAR) and the along track Interferometric SAR (INSAR) imagery of a monochromatic occan wave is presented. The model accounts for the effects of the real aperture radar (RAR) modulation of the radar backscattcr cross-scction. The comparison of the SAR and the INSAR imagery of the wave system under consideration is carried out and the performance of the two imaging systems is studied under various operational conditions. The results of the study indicate that the interferometric SAR is less sensitive to the RAR modulation as compared to the regular SAR. This fact further augments the assertion that INSAR has considerable advantages over SAR in its potential of providing quantitative information about the occan wave lengths, directions and amplitudes.
