摘　　要：介绍了一种新型的短波通信系统CHESS系统,描述了CHESS的系统结构及其关键技术—差分跳频。差分跳频主要归结于一种G函数算法,在介绍G函数算法原理的基础上,提出了一种改进的G函数算法,并对其进行了分析和检验。This paper presents a new HF frequency hopping communication system which is called correlated hopping enhanced spread spectrum (CHESS).The composition of CHESS is discussed. Differential frequency hopping (DFH) which is the key technology and the G function algorithm which is the key of DFH in this system is described. The performance of G function FH pattern is analyzed and tested based on the principle of G function arithmetic.

关 键 词：CHESS 差分跳频 G函数
