The magnetic field integral equation (MFIE) for the scattering of the rough surface of the conductor is solved by a fast iterative numerical method combined with the generalized forward backward method (GFBM) and the spectrumacceleration algorithm (SAA). For the Monte Carlo method One-dimensional Pierson-Moskowitz spectrum rough sea surface and hull targets, numerical simulations of double-station and backscattered echoes of down-looking radar on ship target monitoring in sea clutter environment are given. , And the simulation of the relationship between the sea echo and the target echo and its relationship with the environmental and target parameters, the radar equation calculation of the corresponding target of the received echo and the backscattering coefficient of the sea surface are proposed. The monitoring and interception of CSSC targets and the initiative and semi-active guidance provide a numerical simulation method.
