| Abstract: | 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. |
