摘要
捷联式光学导引头的探测装置直接固联于弹体上,许多现有的制导信息处理方法都不再适用.对半捷联式导引头进行研究,根据其与常平架式与捷联式导引头不同的配置方式,推导了滚仰式和偏航俯仰式半捷联导引头视线转率提取算法,并分析了影响半捷联导引头视线转率提取精度的主要因素及误差传递关系,通过Simulink仿真验证了算法的正确性.
Optical detector of strapdown seeker was fixed rigidly to the missile body,and many traditional guidance information processing methods can not be applied directly.The half strapdown seeker was studied.According to its different structure,reconstruction algorithm of the line-of-sight（LOS） rate was derived for roll-and-pitch and yaw-and-pitch half strapdown seeker.The Influence factors and error transfer relationship for extracted accuracy of LOS rate were analyzed.Then the correctness of the algorithm was verified by Simulink.
