激光制导**半实物仿真系统的弹目视线复现精度是评估半实物仿真精度的一项关键参数。在分析弹目视线运动的静态和动态误差来源的基础上, 采用多体系统理论建立了具有明确物理意义的弹目视线运动模型。对正弦、指数和典型战情三种运动过程中的弹目视线角分别进行了仿真计算和实验测试, 利用实测数据对仿真结果进行了对比验证。结果表明: 弹目视线角仿真结果与实测结果误差小于2.68′, 误差均值小于0.30′, 两者具有较好的一致性, 模型能够准确反映弹目视线角的变化规律。

The precision of line of sight reproduction is a key factor of precision evaluation in Hardware-in-The-Loop(HWIL) simulation system for laser guided weapon. Base on the analysis on static and dynamic errors of line of sight in total, the movetion model with definite physics signification was set up by adopting multi-body system theories. After that, the model was verified by using the measure data of angle of sight in various motion including sine, exponent and typical scenario. The verification shows that the simulation results meet well with the measurement results as the error is less than 2.68′ and average error is less than 0.3′, and the model can describe the variation rules of angle of sight.
