为了解决激光测角弹穿烟长度精确计算问题,文中创新性的提出了采用离散膨胀球模拟烟雾扩散规律的穿烟模型算法,可方便计算出不同侧风风速、地面站摆放位置、弹道规划等对穿烟长度的影响规律。依据某型号导弹的飞行高速录像,修正了烟雾扩展模型,穿烟计算结果与多发实际飞行试验测试结果基本一致,验证了算法的有效性。文中研究成果可以应用在雷达测角、激光测角、红外测角等其他测角制导的武器系统中。

In order to realize the accurate calculation of the passing smog distance of laser angle measurement, a smoke model algorithm using discrete expansion ball to simulate smoke diffusion law was proposed innovatively in this paper, which could conveniently calculate the influence law of different crosswind wind speed, ground station location and trajectory planning and other situations on passing smog distance. According to the flight high speed video of a certain missile, the smoke expansion model was revised, and the calculation results of smoke penetration were basically consistent with the actual flight test results, which verified the validity of the algorithm. The research results can be used in weapon systems of radar angle measurement, laser angle measurement, infrared angle measurement and so on.
