摘要
首先介绍了步进自动跟踪的两种常用方式及其所面临的问题,在此基础上提出了基于梯度步进的最佳路径搜索方法。仿真表明:本文提出的算法,在不影响精度的条件下,运算简单,减少了步进次数。
step tracking is currently considered as the most cost - efficient system at 6/4GHz satellite ground station. This paper described conventional step- track method and analysis its shortcoming. In order to enhance tracking quality, a new method which is based on gradient estimation has been proposed. By simulation, gradient step method is proved to be superior to old ways.
