摘　　要：对于红外空空导弹,在对两轴平台光轴特性进行分析的基础上,针对基于横滚/偏摆结构的两轴平台,提出了一种融合了动态规划思想的光轴超半球稳定算法。通过仿真,检验了光轴稳定的性能。仿真结果表明,文中算法能够实现极坐标框架两轴平台光轴的超半球稳定性,具有较高的稳定精度和快速的跟踪能力,对实际应用具有参考价值。The importance of post-launched missiles in aerial combat was analyzed on the background of air-to-air missile with infrared seeker. The optical axis of platform was analyzed according to the characteristics of two-axis polar coordinate frame platform, an algorithm of optical axis super-hemisphere stabili- zation was proposed for the two-axis platform with rolling/swing configuration. The algorithm was efficiently optimized using a dynamic programming method. The simulated results prove that the algorithm can achieve the optical axis super-hemisphere stabilization with high accuracy and fast tracking capabili- ty. It has a reference value for practical application.
