| 摘 要： | 为有效地消除飞机间相对速度对捕获性能的影响，从阐明相对速度对捕获过程的影响机理入手，根据测量得到飞机平台的运动和振动数据，推导出动态补偿公式，提出了基于动态补偿的空间激光通信捕获算法，并对捕获算法的性能进行了对比分析。结果表明：相对速度严重影响捕获统计覆盖率；为了满足捕获统计覆盖率的要求，采用普通的捕获算法所需要的最大捕获时间和平均捕获时间明显增加；基于动态补偿的捕获算法能大大改善捕获系统的性能，提高捕获概率，减少捕获时间。

| 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. |
