发射区是一个空间区域,当目标处于该空域内不同子域时发射导弹,导弹对目标的杀伤概率不尽相同。为寻求发射区内最佳发射时机,提高导弹的作战效能,对发射区进行等步长离散,计算特征点脱靶量,选取最优发射区域。基于便携式防空导弹仿真平台,以某型便携式防空导弹为算例进行分析,得出发射区内不同子域脱靶量分布的一般规律,为射手和指挥员确定导弹发射时机提供依据。

Launch area is a large space, when target is in different subdomains; the kill probability of missile is not the same. For seeking the best fire time and improving combat effectiveness, the launch area was discrete, the value of miss distance at characteristic point was calculated and the optimal launch area was selected. The method of missile envelops optimization was put forward. Based on simulation platform of portable surface-to-air missile, the simulation result that a certain type of portable surface-to-air missile shooting a certain type of target drone was analyzed, the distribution law of the miss distance in the launch area was obtained, and a reference that how to choose the fire opportunity for shooter and commander was provided.
