Abstract

Abstract: In order to effectively eliminate the influence of relative velocity between aircrafts on acquisition performance, the mechanism of influence of relative velocity on acquisition process is described. According to the measured data of aircraft motion and vibration, the dynamic compensation formulas are derived, an acquisition algorithm based on dynamic compensation in space laser communication is proposed, and the acquisition performance of the algorithm is analyzed. The results show that the relative velocity has a seriouse influence on the statistical coverage of acquisition. In order to meet the statistical coverage of acquisition, the maximum acquisition time and average acquisition time of common algorithms are significantly increased. The acquisition algorithm could greatly improve the performance of acquisition system by increasing the acquisition probability and reducing the acquisition time.

Key words: communication technology, space laser communication, acquisition uncertainty region, acquisition time, acquisition probability
