激光目标模拟器逼真度主要用来评估目标模拟器出射激光对实际场景中激光照射器出射激光在传输及被目标发射时的近似程度。逼真度评估的有效程度取决于评估方案的适用性及实际可操作性。因此, 提出了一种激光目标模拟器模拟逼真度的有效评估方案, 并给出了具体指标的量化逼真度定义。首先给出了实战中的激光能量传输模型和半实物仿真系统中的光斑控制模型, 接着以此为依据重点研究了激光目标模拟器激光脉冲和激光光斑特性的逼真度评估内容, 最后通过计算各分项指标权重, 得出了激光目标模拟器的整体逼真度。逼真度量化评估方案可应用于激光目标模拟器的设计及性能评估, 从而达到在室内完成半实物仿真测试以减少总体测试费用和时间的目的, 对于现代化**系统设计具有十分重要的意义。

The fidelity of laser target simulator is mainly used to evaluate the degree of approximation between the target simulator′s output laser and the laser irradiator′s output laser during its transmission and being reflected by the target surface in actual battlefield. The effectiveness of fidelity depends on the applicability and actual operability of the evaluation scheme. An effective evaluation scheme for studying the fidelity of the laser target simulator was proposed, and the quantized fidelity of every specific indicator was also defined. Firstly, the laser energy transport model of target laser in real battlefield and the control model of light spot in the hardware-in-the-loop simulator were calculated. Then, according to the two models, the fidelity evaluation content of the characteristic of laser pulse and laser spot in the laser target simulator was studied with emphasis. And finally, by calculating the weight of the specific index, the whole fidelity of laser target simulator was obtained. The fidelity evaluation scheme can be applied to the design and performance evaluation of the laser target simulator, so it can reduce the cost and time by doing the test of the laser target simulation in the hardware-in-the-loop simulation system, which means a lot in designing modern weapon system.
