Background
The photoelectric dynamic target is a universal test device for testing the tracking performance of a photoelectric tracking system, and the principle of the photoelectric dynamic target is roughly as follows: the motion of a space target is simulated indoors by using a collimator and a rotating mechanism, a simulated space target with a known track is provided for the tested photoelectric tracking system, and the photoelectric tracking performance of the tested system is detected by tracking the simulated target. Before testing, the photoelectric dynamic target needs to be aligned with the photoelectric tracking system to be tested, so that the vertex of a light cone when the photoelectric target rotates is basically overlapped with the intersection point of a rotating shaft system of the photoelectric tracking system to be tested.
In the rotation process of the photoelectric dynamic target, additional disturbance can be measured due to the shaking of a shaft system, the deformation of a rotating arm and the like, and the disturbance can be superposed into errors of dynamic measurement, so that the dynamic measurement precision of the photoelectric tracking equipment is reduced. At present, aiming at improving the dynamic performance of a photoelectric dynamic target, the method for testing the disturbance quantity in real time mainly comprises the following two methods:
the method comprises the following steps: the device fixes a small reflector on the last reflector of a target, divides a part of parallel light beams emitted by a collimator into light beams, passes through a rotating arm, reaches the back of the target, is fixed on a turning reflector at the tail end of a rotating shaft, converts large-angle motion of the light beams into small-angle motion, and records the real-time change condition of the target light beams by adopting a sensor.
The second method comprises the following steps: the invention discloses a high-precision optical dynamic target device (P) (Benzhenlan and the like, Shanghai optical precision mechanical research institute of Chinese academy of sciences, 2011).
In the method, the detection result in the first method comprises the shaking amount of the motor shaft system and the bending and deformation of the rotating arm, but the light path is relatively complicated to adjust, and when the light path is rotated to the position of the base of the supporting shaft system, the light path is shielded, so that the whole-circle rotation cannot be realized. In the second method, the error caused by the shaking of the motor shaft system can be detected in real time, but the error caused by the bending and deformation of the rotating arm cannot be detected. In addition, the photoelectric tracking system needs to track various targets such as missiles, airplanes and ships in an external field, and the scheme can only provide simple point and line targets and cannot meet the requirements of simulating various targets and complex background environments.
