透射式激光目标半实物仿真系统研究

摘要

According to the homing principle of semi-active laser guided weapons, the main parameters which affect the simulation confidence in the performance test of hardware-in-the-loop simulation are analyzed. The laser target simulator based on the transmission-mode structure is designed. Using this system it can generate laser beams with sparkle size of 0.1 mm to 20 mm. The central point aberration is ±9 mm. The energy range is bigger than 50dB. An experimental system was set up. The results show that the range of laser target simulation is increased effectively by using this transmission-mode structure,while it is more convenient to simulate various characteristics of the laser target.%根据激光半主动制导武器的制导原理,分析了半实物仿真性能测试中影响仿真置信度的重要参量,设计了基于透射式结构的激光目标模拟仿真系统,该系统可实现:光斑大小变化范围0.1～20 mm,抖动范围±9 mm,能量变化范围大于50 dB的模拟,并结合研制需求搭建了演示实验装置.结果表明:透射式结构的采用,有效增大了激光目标的模拟范围,同时有利于激光目标特性的模拟.
