Describes a numerical model which is applicable in the study of wide beam HF ground wave radar's signal processing. Based on the backscatter theories of HF electromagnetic waves from ocean surface, the model contains the combination of the first order peak, the second order sea echo, currents, echo from hard targets, effect of land blocking and noises. Output spectrum from the model possesses typical features of real Doppler spectrum detected by OSMAR2000, and can be used to test the effectiveness of certain space spectrum estimation algorithms as well as sea state parameter inversion methods.
