摘　　要：为了解决激光目标回波模拟器输出脉冲激光能量无法现场标定的问题,采用模拟积分原理,通过光电探测组件参数优化设计和积分组件电路结构设计,建立了激光目标回波模拟器能量标定装置,并设计相应实验对标定装置的测量能力进行验证。结果表明,激光目标回波模拟器能量标定装置可实现对脉冲宽度为10ns~100ns脉冲激光能量值的准确测量,其能量测量范围为10fJ~1pJ,包含因子k=2时,测量不确定度为13.8%。该研究可满足激光目标回波模拟器输出脉冲激光能量测量与标定的需求。In order to solve the problem that the output pulse laser energy of the laser target echo simulator can not be calibrated in the field, the analog integral principle was adopted, the energy calibration device of laser target echo simulator was established through the parameter optimization design of the photoelectric detection module and the circuit structure design of the integral module, and the corresponding experiments were designed to verify the measurement ability of the calibration device. The results show that, the energy calibration device of the laser target echo simulator can accurately measure the laser energy when the pulse width is 10 ns~100 ns and the energy measurement range is 10 fJ~1 pJ. The measurement uncertainty is 13.8% when the inclusion factor k is 2. It can fully meet the requirements of the output pulse laser energy measurement and calibration of the laser target echo simulator.
