| 摘 要： | 针对红外成像导引头弹目视线角速度获取精度较差,无法满足导弹制导指标要求的问题,根据红外导引头角跟踪原理,比较研究了直接微分法、基于马尔科夫模型的方法和基于控制系统工作原理的方法3种弹目视线角速度提取方案。利用试验数据进行了仿真分析。仿真结果表明:直接微分法和基于马尔科夫模型的方法均不适用于红外成像导引头弹目视线角速度提取。将控制系统设计为二阶无静差系统,并以此建立了基于控制系统工作原理的弹目视线角速度提取模型。仿真分析表明:该方法适用于红外导引头弹目视线角速度提取。

| Abstract: | The infrared imaging seeker has poor accuracy of line-of-sight angle rate, which cannot meet missile guidance requirements. Based on the infrared seeker angle tracking principle, the direct differential method, the Markov modeling method and the control system modeling method are used to extract line-of-sight angle rate of the infrared seeker. Experimental data are used to conduct the simulation analysis. The simulation results show that both the differential method and the Markov modeling method are not suitable for the extraction of line-of-sight angle rate of the infrared seeker. Based on the target-tracking principle of the seeker and control system characteristics, the infrared seeker angle-tracking-loop is designed as the type II control loop for zero steady state pointing error. The line-of-sight angle rate extraction method based on the control system is proposed. The simulation result proves that the control system modeling method can extract line-of-sight angle rate of the infrared seeker accurately. |
