Other Abstract

Prediction for laser ranging of non-cooperative target is extrapolated from the Two Line Elements (TLE) normally, which has relatively large deviation and affects the success rate of laser ranging mission. Based on the orbital theory and the measured data of space target, the deviation of the forecast is mainly due to the deviation of mean anomaly from the prediction model and the real mean anomaly of the spatial target in the orbit. According to the target's miss distance in the field of view of tracking telescope, the relative algorithm can be used to find the optimal time element deviation to correct the mean anomaly of the spatial target. After modification, the visual position deviation of the space target is improved, the distance deviation can be reduced from several hundred meters to tens of meters, which makes the echo arrival time expectation more accurate, and can provide a more precise range gate control for the single-photon detector, and improves the mission success rate of laser ranging.
