摘要
步进跟踪在低成本动中通跟踪系统的设计中得到了广泛的应用。在对动中通跟踪问题分析的基础上,对双向搜索式的步进跟踪原理进行了研究,并对算法的实现进行了设计,同时给出了具体工作步骤。对影响步进跟踪算法的关键因素步长的选择进行了仿真验证,结果表明,选择合适的步长能够有效地减少步进次数。
The step tracking is widely used in the design of low-cost Satcom-On-The-Move （ SOTM） system,and it is considered as the most cost-effective system design.The principle of step tracking based on bidirectional search is studied and the working process is designed based on analyzing the tracking problem for SOTM in this paper.At last,the simulation experiment is done for the step size selection,which is considered as a key factor impacting the step tracking algorithm,and the results show that the appropriate step size selection can reduce step times effectively.
