Aiming at the problem that the two-dimensional uniformity of the frequency hopping pattern in differential frequency te01-4147c hopping communication is poor, and the frequency hopping frequency is easy to be eavesdropped, this paper designs an encryption scheme based on the pseudo-random sequence of logistic chaotic map to randomly scramble the frequency hopping pattern.After verification, the differential frequency hopping godzilla minus one ginza pattern after encryption and scramble is compared with the original frequency hopping pattern.Although the performance of the system is reduced, the correlation between frequencies is reduced, and the two-dimensional uniformity is improved, which has strong anti-deciphering ability.
