以激光制导**半实物仿真系统为背景，对激光目标模拟器进行了分析研究，设计了一套实时性好、精度高的激光目标模拟器。对该激光器的组成及设计方案进行了论述，并重点对其中的实时能量衰减系统和可控扩束系统进行了研究和设计。仿真试验结果表明，该激光器能实时模拟激光光斑能量及大小的变化，满足了激光制导**半实物仿真的需求。

Taking the Hardware-in-the-loop (HWIL) simulation of laser guided weapons as the background, we studied the laser target simulator in the paper, a suit of high precision and real-time laser target simulator was designed. The composition and design of the laser were discussed, focusing on the system of energy attenuator and controllable telescope. Experimental results show the laser simulator can simulate the energy and size of laser facular, and meet the need of HWIL of laser guided weapons.
