摘要
提出了一种应用于跳频扩频系统的自适应捕获策略。在基于滑动相关捕获的基础上 ,自适应捕获策略能够充分利用有利的环境迅速完成捕获。首先描述了自适应捕获策略和其同步互控流程 ,接着分析了自适应捕获策略对 FH系统抗干扰性能的影响 ,最后还分析了其平均捕获时间性能。
An adaptive acquisition strategy for slow frequency hopping spread spectrum system is proposed. Based on the slow and correlation acquisition technique, the adaptive acquisition strategy can make full use of transient friendly environment and complete acquisition quickly. A general description of the strategy and the synchronization flow is given at first, then the effect of the adaptive acquisition strategy to the anti jamming performance of slow FH systems is analyzed. Finally, the mean time to acquisition performance is also analyzed and presented in detail.
