某船载无人操控天线末段跟踪的数引策略改进

Improvement of Digital Guide Model for Shipborne Unmanned Antenna's Terminal Tracking

从无人操控天线需要依赖数引完成目标自动捕获以及现有的主动段航天测量的数引模型精度不够的背景出发,指出提高数引精度即进行数引改进的必要性。然后结合末段跟踪的特殊性,从时差、视差和延时累积误差三个影响数引精度的最主要方面详细分析了它们的形成机理,并给出了各自的改进方法。

In the background that the unmanned antenna depends upon the digital guide to accomplish the automatic capture of the target,and the original model of digital guide for initiative aerospace measurement has not enough accuracy,this paper points out the necessary of improving the digital guide's accuracy.Integrated with the particularity of terminal track,the principles of three major errors of digital guide which are the time difference,visual difference and delaying accumulation error are analyzed and the improving methods aiming at each error are given.
