摘　　要：利用光电跟踪系统实时测量导弹类飞行目标已成为靶场测试手段的发展趋势之一,光电跟踪系统需要具备高精度跟踪高速飞行目标、实时输出目标飞行轨迹数据以及目标飞行姿态等实时图像信息。提出一种新型车载光电弹道测量系统,应用高强度轴承改善角位置输出的稳定性;利用再生反馈控制技术抑制跟踪快速目标时产生的滞后误差,提高光电弹道系统的测量精度;将测量数据归一化为垂线测量坐标系中的测量值,以20ms的刷新率对外输出;提出模拟航路检测方式,可在野外条件下完成对光电设备性能检测,实际稳态跟踪精度可达到0.21mrad。Electro-optical tracking systems are widely used to make the real-time measurement of flying targets in test field due to their capabilities of tracking high speed targets precisely,as well as providing flight path data and flight attitude image in real time.A novel vehicle-borne electro-optical trajectory measurement system is presented.Rigid bearings were used to improve the stability of angular position output.Regenerative feedback technology was applied to suppress lagging error when a high-speed target was tracked.Measurement data with 20 ms update rate were normalized to rectangular coordinates to make data analysis conveniently.Besides,a simulated trajectory detection method to test system in the field is put forward.The system is flexible to be deployed and is able to measure trajectory of flying target promptly and precisely.The steady-state tracking accuracy can reach 0.21 mrad.
