Research on Accurate Control of Energy in Calibration System of Threshold Value of Laser Seeker

精确能量控制是激光寻的制导武器导引头阈值标定系统的最主要功能,关系到导引头阈值标定的准确性和可信度。在分析实验室环境中激光光程分析的基础上,从两个途径提高能量控制的精确度通过理论计算和试验的手段,建立了实验室环境中精确的激光传输模型。实验表明,该系统采用的措施是有效的,精确激光衰减建模是正确的,能量精确控制范围下限可远低于10^(-15)J,适用于各种激光寻的式导引头的阈值标定。

Accurate control of energy was the primary function,which affected the accuracy and confidence level of the calibration of laser seeker's threshold value.Based on the laser transmission analysis in the lab.two main approaches to improve the precision of energy control were considered,it is shown that the adopted measures are effectual and the ac- curate laser transmission models are exactitude,and the lower limit of energy accurate control range can be much less than 10^(-15)J.so the system is applicable to threshold value calibration of all kinds of laser homing laser.
