研究了一种配有激光近炸引信的防空导弹毁伤效果评估仿真方法。以仿真软件Vega为基础,实现了弹目交会的视景仿真;应用碰撞检测技术模拟激光近炸引信的目标探测。并利用包围体方法提高碰撞检测速度,解决了目标遗失问题;通过计算破片击中目标的数量和部位,实现了对导弹毁伤效果的量化评价。在此基础上,开发了“防空导弹毁伤效果评估”仿真软件,并在导弹引信设计中进行应用,验证了算法的有效性。
A simulation method for evaluating the damage effect of antiaircraft missiles equipped with laser near fuze is studied. Based on the simulation software Vega, the scene simulation of the projectile is realized; the collision detection technology is used to simulate the target detection of the laser near-explosion fuze. The method of bounding body is used to improve the speed of collision detection and solve the problem of target loss. The quantitative evaluation of the missile damage effect is achieved by calculating the number and location of targets hit by the fragment. On this basis, the “air defense missile damage evaluation” simulation software was developed and applied in the design of missile fuses, which verifies the effectiveness of the algorithm.
