摘　　要：随着电子设备的种类和数量的日益增多,电磁环境日益复杂,为保证全球卫星导航系统(GNSS)终端设备的正常运行,需要及时查找和排除干扰源,其中干扰源测向技术是核心技术之一.本文对比幅法、比相法、空间谱等多种干扰测向方法的优劣性进行了对比分析,对确定合理有效的干扰源测向技术及相关设备的研制有重要意义.With the increasing types and quantities of electronic equipment,the electromagnetic environment is becoming more and more complex.In order to ensure the normal operation of GNSS terminal equipment,it is necessary to find and eliminate the interference sources in time.Among them,the direction finding technology of interference sources is one of the core technologies.This paper makes a comparative analysis of the advantages and disadvantages of various interference direction finding methods,such as amplitude comparison method,phase comparison method and spatial spectrum method.It is of great significance to determine the reasonable and effective direction finding technology of interference sources and the development of related equipment.
