基于随机拟合的悬浮式深弹弹阵特征建模*

摘要

The coordinate calculation model of the depth bomb impact point is established by analyzing the air trajectory characteristics of suspended depth charge. The impact point coordinates for single and six mounted rocket depth bombs on considering ship state in six-dimension freedoms are simulated by using the Monte-Carlo method. The distribution characteris-tic for the impact ponit is analyzed and the joint density function is obtained. It is shown that when the launch parameters contain normal perturbations,the impact points are located in a near elliptic area and the impact point coordinates still show a normal distribution.%通过分析悬浮式深弹发射后在空中的弹道特性，建立了深弹弹着点坐标的计算模型。采取蒙特卡洛方法，分别对舰艇六自由度状态下，单管和六联装火箭深弹的弹着点坐标进行了仿真计算，对弹着点的分布规律进行了研究，并得出弹着点的联合密度函数。结果表明，在发射参数存在正态扰动时，弹着点散布区域均呈椭圆形分布，弹着点坐标均仍服从正态分布。
