Abstract :
A hybrid approach of the generalized forward-backward method (GFBM) with the spectral accelerate algorithm (SAA) and Monte Carlo method is developed. It is applied to numerical simulation of angular radar echo from a rough sea surface with a ship presence as TE or TM tapered waves are incident upon it. Due to the high efficiency of the GFBM/SAA, radar echo at low grazing angle (LGA) can be also calculated. Numerical simulations show the functional dependence upon polarization, observation angle, sea surface wind speeds, ship location and other parameters.
