Abstract :
A numerical simulation model of shallow sea topography imaging by Along-Track Interferometric SAR (ATI-SAR) is introduced according to its imaging mechanism. This simulation model is used to study the influence of radar parameters (frequency, incidence angle, baseline length and polarization) on one dimensional sand wave imaging by ATI-SAR. The simulation results indicate that high frequency, VV polarization, an incidence angle of 50° and long baseline length may be favorable to shallow sea topography imaging by ATI-SAR when the imaging time lag between two antennas is shorter than the de-correlation time of the sea.
