【摘要】 在鱼雷弹道仿真中,常见将目标作为质点处理。这样虽能简化问题,在鱼雷古典导引律研究及鱼雷自导系统远距捕获目标概率研究等方面较为可行,但对于鱼雷近程探测、跟踪及攻击弹道仿真却不适宜,尤其是精确制导弹道的仿真。该文在研究声自导鱼雷末弹道特性的基础上,提出了针对潜艇目标的艏、艉二亮点特征的椭球体目标建模方法,将目标几何模型与声学模型结合起来。此模型已在若干仿真工程中得到了验证和应用。更多还原

【Abstract】 In torpedo trajectory simulation, the target entity is often regarded as particle. This method simplify the trajectory research, and is often used in research of detecting probability at remote range and of the torpedo classical guiding methods. But it lost precise and creditability. It isn′t adept to apply this method in research of tracking guidance and terminal phase guidance any more, especially not in research of precise guidance. Considering the disadvantage above, we present a ellipsoid modeling method based on two highlights structure for submarine in antisubmarine simulation. And the ellipsoid modeling method has been applied in some simulation projects.更多还原
