Simulation of Electromagnetic Scattering Experiments in the NSWC Carderock MASK Facility

Abstract : Radar scattering experiments performed in the NSWC Carderock Maneuvering And Sea-Keeping (MASK) wavetank facility are simulated using computational and analytic solutions. Forward scattering over a rough sea surface is simulated. as well as the backscatter from plate targets suspended over the rough surface. The generalized forward backward method is used to simulate the measurements with a 2D model and a reduced order iterative physical optics method is used for a 3D model. Monte Carlo data sets for multiple surface realizations are generated to extract the coherent and incoherent scattering from the computer simulations.
