Bistatic radar imaging of the marine environment. Part II: simulation and results analysis

Abstract : We present a bistatic, polarimetric and real aperture Marine Radar Simulator (MaRS) producing pseudo-raw radar signal. The simulation takes the main elements of the environment into account (sea temperature, salinity, wind speed). Realistic sea surfaces are generated using a two-scales model on a semi-deterministic basis, so as to be able to incorporate the presence of ship wakes. Then, the radar acquisition chain (antennas, modulation, polarization) is modeled, as well as the movements of the sensors on which uncertainties can be introduced, and ship wakes. The pseudo raw, temporal signals delivered by MaRS are further processed using, for instance, bistatic synthetic aperturebeamforming. The scene itself represents the sea surface as well as ship wakes. The main points covered here are the scene discretization, the ship wake modeling and the computational cost aspects. We also present images simulated in various monostatic and bistatic configurations and discuss the results. This paper follows “Bistatic radar imaging of the marine environment. Part I: theoretical background”, where much of the theory used here is recalled and developed in detail.
