摘　　要：在红外成像制导半实物仿真仿真实验中架设导引头和目标模拟器过程中的安装误差是不可避免的,为提高试验中制导精度和仿真可信度,分析了误差产生的原因并建立了安装误差静态的数学模型和修正方法。通过分析目标模拟器像元中心的运动轨迹对安装误差进行分类判断,进而推导了安装误差的数学模型,并应用OpenCV对导引头制导图像进行处理,获得求解误差模型所需的坐标信息,最后对弹道制导模型进行了修正,通过仿真验证定量地分析了误差修正对脱靶量的影响,对制导攻击效果有一定的优化作用。Installation errors in the process of erecting the seeker and target simulator are inevitable in infrared imaging guidance semi-physical simulation experiments.In order to improve the guidance precision and simulation credibility of the test,a static mathematical model and correction method for the installation error are established by analyzing the causes of the error.Analysis of the motion trajectory of the target simulator cell center allows classification of the installation error,following which the mathematical model of the installation error is derived.OpenCV is used to process the seeker guidance image.Next,we obtain the coordinate information needed to solve the error model,and finally,we modify the ballistic guidance model.The simulation verification is conducted to quantitatively analyze the influence of error correction on the miss distance,which has a certain optimization effect on guidance attack.
