摘要
针对X波段导航雷达海浪特性研究的需要,对海浪进行了数值模拟。采用经典PM谱作为靶谱,利用Longuest—Higgins模型仿真海浪,然后对仿真的海浪进行阴影调制和倾斜调制得到调制后的雷达图像,并经过海浪谱反演技术验证了仿真的可行性和准确性。
Aiming at the need of the study of the characteristics of the wave of the x-band navigation radar, the numerical simulation has been done. Using the classical PM spectrum as the target spectrum, the Longuest-Higgins model is used to simulate the waves, and then the simulated waves are subjected to shadow modulation and tilt modulation. The modulated radar images are obtained and the feasibility and accuracy of the simulation are verified by the wave spectrum inversion technique.
