垂直冷发射防空导弹弹道设计中的参数优化

根据垂直冷发射防空导弹的飞行程序，分析了影响弹道性能的主要因素，选取相应的参数对弹道进行优化设计。优化前后弹道参数的计算结果表明，该优化方法改善了速度特性，在攻击超低空目标时保证弹道末段俯冲角满足布儒斯特角的要求，是防空导弹弹道的有效设计方法。

Parameters Optimization in Trajectory Design of Vertical Cold Launch Air-Defense Missile

According to the flight course of vertical cold launch air defense missile, the major factors that affect the trajectory performances are discussed in this paper. The corresponding parameters are selected to optimize trajectory. The computed results before and after optimization are showed that the optimal method improves the speed characteristic, and the trajectory end dive angle is met the requirement of Brewster angle when ultralow altitude target is stroked by air defense missile.
