分析了合成孔径雷达( SAR)探潜对随机粗糙海面特性的应用需求和随机粗糙海面的生成机理,计算了满足Gauss形态相关函数的随机粗糙海面后向散射系数,提出了高海况下考虑海浪遮蔽效应的潜艇海面兴波尾迹的后向散射计算方法.仿真结果表明,海浪遮蔽效应会使海面后向散射降低从而更接近于海面散射的真实值,且其具体降低量与海况等因素有关.

@@@@The application demand of submarine detection for random rough sea surface by synthetic aperture radar(SAR), as well as the generation mechanics, is analyzed . The backscattering of the random rough sea surface with Gaussian form correlation function is calculated . The calculation method which considers the shadowing effect of the sea wave under high sea state is proposed . Simulation results indicate that the shadowing effect of the sea wave can reduce the sea wave backscatter and make it closer to real value of backscattering . The reduction amount depends on many factors such as the sea state .
