【摘要】：为提高红外制导半实物仿真试验精度和可信度,研究和分析了红外制导半实物仿真系统误差。详细分析了影响红外制导半实物仿真精度的主要误差源和产生机理,从仿真机理角度建立了半实物系统仿真模型和系统误差模型,通过仿真和分析比对在有无加载误差模型下的导弹弹道解算结果,定量分析各类误差源对仿真试验精度的影响。通过仿真分析表明,转台性能和机械误差对仿真试验精度影响很小并可忽略,而红外导引头轴向位置安装误差影响较明显,在仿真试验过程中需要重点考虑并保证在厘米级范围内。
[Abstract]:In order to improve the accuracy and reliability of the hardware-in-the-loop simulation test for infrared guidance, the error of the hardware-in-the-loop simulation system for infrared guidance is studied and analyzed. In this paper, the main error sources and generation mechanism that affect the accuracy of hardware-in-the-loop simulation of infrared guidance are analyzed in detail. The simulation model and error model of hardware-in-the-loop system are established from the point of view of simulation mechanism. Through the simulation and analysis of the missile trajectory calculation results with or without the loading error model, the influence of various error sources on the simulation test accuracy is quantitatively analyzed. The simulation results show that the performance of the turntable and the mechanical error have little effect on the accuracy of the simulation test, while the axial position error of the infrared seeker is more obvious. In the process of simulation, it is necessary to consider and ensure in the centimeter range.
