摘要：The synchronization technology is one of the key technologies in fast frequency hopping communication system. The performance of synchronous loop will directly affect the whole performance of the fast frequency hopping communication system. In view of the deficiency of synchronization time and synchronization anti-interference in the existing synchronization methods, an improved synchronization acquisition method is put forward, that is double judgment circular correlation method. The test results show that the improved synchronization acquisition method can effectively improve synchronization speed, increase synchronization anti-interference performance and reduce the complexity of synchronization loop.
