Study on radar imaging simulation of ocean current and waves

Monitoring ocean surface current is one of the most important applications for microwave remote sensing. It is significant for both civil and martial maritime activities. Microwave sensors mainly include early RAR, high-resolution SAR, and Bistatic SAR which is newly arisen[1]. A simulation procedure for RAR/SAR/biSAR with parallel flight squint mode imagery of ocean surface distributed targets is presented in this paper. With the use of ocean surface current file, sea state and radar parameters, and take tilt, hydrodynamic and velocity bunching modulation into account, this procedure can generate simulated radar imagery, based on the ocean surface scattering model and radar echo model. Radar imagery generated by this procedure can provide simulated data source for sequent algorithms research, i.e., ocean targets detection.
