为了实现对飞机等远距离空中目标运动参数的实时测量，设计了目标自动跟踪测量系统，并对该系统的硬、软件组成及关键技术进行了研究。组建验证样机，进行软件框架设计及功能模块分析，通过实测实验详细测试了系统的工作性能。静态验证实验结果表明：测距结果稳定在1mm 以内，方位测量结果稳定在5″以内。动态验证实验结果表明：对运动目标的实时测距误差为2mm，实时测距频率为5Hz；方位测量误差为0．05°，姿态测量误差维持在0．2°以内，方位和姿态实时测量频率均为20Hz。因此，系统满足空中目标运动参数稳定可靠、高精度的自动实时测量需求。

An automatic tracking measurement system was designed to achieve real-time measurement for motion parameters of long-range air targets,such as aircraft.Hardware,software and key technologies were described in this system.The prototype was made and tested,the software structure design and corresponding functional modules were analyzed.Multiple experiments are presented to testify the working performance of the system.The static verification experiment indicates that the ranging results are stable within 1mm and the azimuth measurement results are stable within 5″.And the dynamic verification experiment indicates that the ranging error of moving target is 2 mm,the ranging frequency is 5Hz,the azimuth measurement error is 0.05°,and the posture measurement error is maintained at a level less than 0.2°,the real-time measurement frequency of azimuth and posture are 20Hz.From the above analysis,the system can provide a stable,reliable and high precision automatic real-time measurement when testing motion parameters of aerial target.
