摘要
研究雷达导引头对导弹制导系统控制的影响,采用在导弹半实物仿真系统,对导引头安装误差会引入闭环仿真回路,使得制导控制系统性能发生变化,影响半实物仿真的逼真度。以雷达导引头安装误差引起的目标视线角误差为研究对象,深入分析误差产生原理并建立了误差数学模型,在分析其对制导控制系统影响的基础上,提出了解算前误差修正和目标辐射位置修正两种形式的误差补偿算法。仿真结果表明,两种算法均可解决导引头安装误差带来的目标视线角误差问题,在实际工程中可根据系统具体特点及仿真要求对误差补偿算法进行选择,都可取得较好的结果。
The installation error of seeker in missile hardware-in-the-loop simulation system introduced into the closed loop can deteriorate the performance of the guidance and control system,which influences the fidelity of simulation.Rresearch on the measure error of target angle induced by installation error of Radar seeker is done on the base of error analysis and modeling.Meanwhile,two sorts of error compensation arithmetic proved effective by simulation are presented.The two methods that consist of the amendment before computing and the amendment to target position can be selected according to the characteristic of simulation system and the special application.
