摘　　要：针对激光引信在探测海面目标时易受海面散射导致引信产生虚警引起早炸的问题,基于线性叠加法和线性滤波法2种海浪谱建模方式完成了JONSWAP谱和文氏谱海面模型的创建,利用几何光学的方法完成海面激光束模拟,使用Matlab仿真分析了不同入射角和不同海情对激光引信海面回波的影响。仿真结果表明:当风速一定时,随着入射角的增大,激光引信海面回波能量逐渐减小,激光束入射角为0°时,海面的反射回波最大;当激光束入射角一定时,随着风速的增大,激光引信海面回波能量逐渐增大。该方法可为后续研究激光引信抗海杂波干扰提供技术支撑。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.
