摘　　要：面向基于微波光子一体化信号处理与数字化的快速、大范围跳频接收机,设计并实现了自动同步捕获方案。所设计的同步方案基于直接功率探测-顺序搜索算法,利用现场可编程门阵列控制并调整本地接收跳频图案的时序,实现了切换时间约为4 ms、跳频频率达到33 GHz的跳频信号的自动同步捕获接收。An automatic synchronous capture scheme is designed for a fast and large-range frequency hopping receiver based on integrated signal processing and digitization of microwave photons.The designed synchronization scheme is based on direct power detection and serial search strategy.A field-programmable gate array is used in the experiments to control and adjust the timing of locally received frequency-hopping patterns.The automatic synchronous capture receiving for frequency hopping signals with a switching time of~4 ms and a hopping frequency up to 33 GHz is realized in the experiments.
