摘　　要：差分跳频是近年出现的一种新型扩频通信技术,它集跳频图案、信息调制与解调等功能于一体,构成与传统跳频技术完全不同的技术体制。全面介绍了差分跳频的基本原理和关键技术,分析了DFH系统与传统跳频系统抗干扰能力的异同。Differential frequency hopping （DFH） is a new spread spectrum communication technology whose functions combine FH pattern,information modulation and demodulation, forms different technology structure from traditional frequency hopping（FH） technology. This paper introduces thoroughly fundamental and key techniques, analyzes the similarities and differences of antiamming ability between the DFH system and the traditional HF system. At last the advantages and the existing questions of the technology are presented.

关 键 词：差分跳频 G函数 抗干扰 跳频图案
