激光制导武器能量仿真系统设计

Design of energy simulation system for laser guided weapons

为了实现对激光制导武器半实物仿真系统中能量的精确控制,采用理论分析和工程实践相结合的方法,设计了能量仿真系统,对能量衰减模型及系统设计方案进行了研究,对其中激光生成子系统和能量衰减子系统进行了优化设计,并利用E1000激光能量计对设计的系统进行了标定。结果表明,该系统在不同频率下生成的能量稳定在40mJ左右,可变衰减比范围优于47dB。该系统的实时性和精度均满足半实物仿真中激光能量模拟的要求,且稳定可靠。

In order to control the energy precisely in the hardware-in-the-loop for laser-guided weapons, an energy control system was designed. Combining theoretical analysis and engineering practice, the energy attenuation model and design of the laser were discussed, focusing on laser energy generation subsystem and attenuation subsystem. Finally, this system was calibrated with an El000 laser energy detector. Experimental results show the energy generated by the laser system kept 40mJ at different frequencies, and the range of variable attenuation was greater than 47dB. The system meets the need of energy simulation of laser guided weapons in the character of real time and precision.
