摘　　要：针对实验室环境下单光束脉冲激光测速仪校准问题,本文提出了一种移动目标模拟器的设计与实现方法,该方法基于时间延迟的高精度脉冲序列的产生原理。文中设计了特定的延时脉冲序列,通过软件编程,控制数据定时发生器作为硬件电路生成设备,完成了延时脉冲序列的存储分配和电路生成,实现了具有任意标准速度的通用移动目标模拟器,并构建了激光测速仪检定装置。实验结果表明装置具有较好的测量重复性。Aiming at the calibration problem of single beam pulse laser velocimeter in laboratory environment,this paper presents a design and implementation method of moving target simulator,which is based on the generation principle and implementation method of high-precision pulse sequence with time delay.In this paper,a specific delay pulse sequence is designed.Through software programming,the data timing generator is controlled as the hardware circuit generating equipment.The storage and distribution of the delay pulse sequence and the circuit generation are completed.The universal moving target simulator with any standard speed is realized,and the laser velocimeter verification device is constructed.The experimental results show that the device has good repeatability.
