系统误差分析红外制导半实物仿真 system error analysis infrared guidance HWIL

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

To improve the precision and credibility of infrared guidance hardwave in loop(HWIL) simulation test, the system error of infrared guidance HWIL simulation was studied and analyzed. The main error source of infrared guidance HWIL simulation system and mechanism was analyzed in detail, the guidance HWIL simulation model and the system error model were established from the perspective of the simulation mechanism. Based on the comparison and analysis on the missile trajectory calculating result with or without the loading error model, the influence of various error sources on the simulation test accuracy was analyzed quantitatively. The simulation analysis shows that the error of turntable mechanical and performance have little impact on precision of simulation test and can be ignored, and the effect of infrared seeker axial position error is obvious, needs to be addressed in the process of simulation test and to ensure that within a certain error range.
