Research on lead calculation of photoelectric collimator

The lead calculation of photoelectric collimator is the important performance index to realize the accurate shooting. This paper introduces a kind of detection method for the lead calculation. In order to simulate the real trajectory, the PMAC card as a digital controller, ensure the servo control system to track the given flight-path. According to the flight-path coordinate and equation, the simulation detection model of the lead of pitch and azimuth is deduced by method of parabola interpolation. The theory and experiment show that it is reliable to detect the accuracy of the lead calculation of the photoelectric collimator.
