In frequency hopping communication, the performance of the G function directly affects the performance of the differential frequency hopping signal. On the basis of studying the construction method of traditional G functions, a new construction method of G functions based on chaos mapping is given. This method has the advantages of simple structure and easy control. Simulation results show that the constructed G function has good randomness and uniformity, which is of great significance to improve the performance of differential frequency hopping signal.
