| Abstract: | 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. |
