Research on photoelectric tracking performance test system based on multiple target motion modes

为评价光电跟踪系统的跟踪性能,提出一套光电跟踪性能测试系统,该系统采用高精度电机控制准直系统焦平面处的靶标进行圆周运动、正弦运动及用户自定义运动,可模拟运动特性复杂的目标,准直系统采用透射式中长波光学系统,与反射系统相比,视场更大,同时电机控制精度高,可实现实验室内对跟踪系统最大角速度、最大角加速度的高精度测试。

To evaluate the tracking performance of photoelectric tracking system,a set of photoelectric tracking performance test system is proposed.High-precision motors are used to control the target at the focal plane of the collimation system for circular motion,sine motion and user-defined motion,which can simulate targets with complex motion characteristics.The collimation system adopts transmissive medium and long wave optical system,which has a larger field of view compared with the reflective system;while the motor control accuracy is high,which be used for high precision testing of tracking maximum angular velocity and tracking maximum angular acceleration in the laboratory.
