本文系统地阐述了作为掠海飞行导弹背景的海浪和阵风的数字仿真方法,着重研究了在运动物体上所观察到的海浪和阵风的频谱,引入了表观频谱和表观频率的概念,在大量仿真的基础之上,给出了波迭加法的参数选取方法,还将频谱所给海况参数与模拟所得参数进行了比较。 This paper systematically expounds the numerical simulation of waves and gusts as the background of sea-skimming missiles. It focuses on the observed frequency spectrum of waves and gusts on moving objects, introduces the concepts of apparent spectrum and apparent frequency, Based on a large number of simulations, the method of parameter selection for wave additive method is given, and the parameters of sea state and spectrum obtained from spectrum are also compared.
