【摘要】 依据反舰导弹激光引信掠海高速飞行的背景需求,进行海浪的建模与仿真,海杂波是激光引信用于反舰导弹的典型环境干扰因素,需要建立较理想的海浪模型来研究抗海浪干扰问题。提出基于PM海浪谱的随机海浪模型,该模型应用能量等分理论,并利用线性叠加法进行了海浪的仿真。采用谱估计中的协方差法进行模型校验,经验证表明提出的方法是行之有效的。更多还原

【Abstract】 Sea wave is modeled and simulated to meet the practical need for laser fuze flying over the sea.Sea clutter is a typical environment disturbance to the laser fuze used for anti-ship missile,so an ideal sea wave model should be established for anti-disturbance of sea wave.In this paper,a random wave model based on PM spectrum is established by using energy equipartition theory,and sea wave is simulated by using linear superposition method.Finally,the validity of the proposed model is verified by the covariance method.A number of simulations show that the proposed method is effective.更多还原
