摘要

针对差分跳频通信中跳频图案二维均匀性差，跳频频率易于被窃听的难题，文章设计了一种基于logistic混沌映射的伪随机序列来对跳频图案进行随机扰乱的加密方案。经校验，加密扰乱后差分跳频图案相对于原来的跳频图案，虽然降低了系统性能，但减少了频率之间的相关性，改善了二维均匀性，具有较强的抗破译能力。

Abstract

Aiming at the problem that the two-dimensional uniformity of the frequency hopping pattern in differential frequency 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 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.
