全球定位系统的抗干扰技术研究

摘要

This paper introduces the jam source and jam methods, it expounds the principle and implementation of the routine anti-jam method from both the constellation of GPS satellites in transmitting system and the GPS receiver. The methods of the anti-jam from the GPS receiver are classified and all the anti-jam methods are analyzed from the implementation and the principle, the background of the application and defects of every kind of the anti-jam methods are also given out, it points out that we should choose the right anti-jam technique in view of actual application.%介绍了全球定位系统（GPS）的干扰来源和方法，从GPS卫星星座发射端和用户接收端两方面介绍了常用的抗干扰措施的原理和实现方法。对用户接收端实现的抗干扰技术进行了分类，详细分析了各种抗干扰技术的实现方法和原理，应用背景及局限性，指出了在实际应用中应根据需要灵活选取抗干扰实现方法。
