摘　　要：针对某型反坦克导弹半实物仿真环境中构成环节复杂多样,出现误差呈现不同类型的问题,提出了一种基于该环境下的系统误差分析方法。通过分析仿真计算机、飞行运动模拟器、目标模拟器与仿真专用接口的构成特征与误差特性,得出仿真计算机的延时误差,飞行运动模拟器的机械安装误差,目标模拟器的延时误差与仿真专用接口的传输误差。通过对比各环节局部误差得出误差对仿真结果的影响。提出系统误差补偿方法,对该半实物仿真系统进行修正,通过仿真试验数据得出补偿修正有效。Aiming at the complex and diverse components in the semi-physical simulation environment of a certain type of anti-tank missile,the errors present different types of problems,and a systematic error analysis method based on the environment is proposed.By analyzing the composition characteristics and the error characteristics of the simulation computer,flight motion simulator,target simulator and simulation dedicated interface;the delay error of the simulation computer,the mechanical installation error of the flight motion simulator,the delay error of the target simulator and the transmission error of the simulation dedicated interface are acquired.Furthermore,by comparing the local errors of each link,the effects of the errors on the simulation results are obtained.The system error compensation method is proposed,and the semi-physical simulation system is modified.The simulation test data are used for the compensation correction.
