首先介绍了某型激光制导空地导弹掠靶高飞故障原因,是在某些环境使用条件下导引头输出斜率散布偏大和导引头跟踪能力异常下降引起,并对其产生机理进行分析。其次提出一种导引头输出斜率温度补偿算法,对该算法的设计步骤及有益效果进行阐述,最后通过数学仿真、半实物仿真、飞行试验结果证明,采取该温度补偿算法,可有效解决该导弹掠靶高飞问题,提高导弹命中精度。

This paper first introduced the skimming off the target fault of the Laser-Guided Missile Weapon System, under the condition of certain environment using seeker output slope spread and inefficiency caused abnormal seeker tracking ability decline, and its mechanism were analyzed, and the second presents a seeker output slope temperature compensation algorithm, the design of the algorithm steps and beneficial effects, at last, by mathematical simulation, hardware-in-the-loop simulation and flight test results show that take the temperature compensation algorithm, can effectively solve the skimming off the target fault, accuracy can be obviously improved.
