扩频技术的应用已有30多年的历史，在通信系统中的应用也已相当成熟，将扩频技术用于无线电引信，可使引信具有许多优良性能。首先，论述扩频的基本原理和主要特点，然后，介绍扩频技术在引信中的应用，并提出一种采用FH－DS混合扩频技术的方案。
The application of spread spectrum technology has been more than 30 years old, and its application in communication system has also been quite mature. The use of spread spectrum technology in radio fuze can make the fuze have many excellent performances. First of all, the basic principles and main characteristics of spread spectrum are discussed. Then, the application of spread spectrum technology in fuze is introduced and a scheme using FH-DS hybrid spread spectrum technology is proposed.
