Abstract:	Aiming at the problem that laser fuze is prone to false alarm and early explosion due to sea surface scattering when detecting sea surface targets, JONSWAP spectrum and Wenckell spectrum sea surface models are created based on two wave spectrum modeling methods (linear superposition method and linear filter method), and geometric optics method is used to simulate sea surface laser beam. The influence of different incidence angles and different sea conditions on the sea echo of laser fuze is analyzed by Matlab simulation. The simulation results show that when the wind speed is constant, the echo energy of the laser fuze decreases gradually with the increase of the incidence Angle. When the laser beam incidence Angle is 0°, the reflected echo of the sea surface is the largest. When the incidence Angle of laser beam is constant, the echo energy of laser fuze increases gradually with the increase of wind speed. This method can provide technical support for the subsequent study of laser fuze anti sea clutter interference.
