Abstract: Satellite navigation has been widely used in various fields of human production and life, however, due to weak landing signals and other reasons, satellite navigation signals are prone to interference. In practical applications, distributed suppression jamming has become an effective means of satellite navigation jamming because of its advantages such as large coverage area and difficult detection. In this paper, the visual field algorithm based on the reference surface is used to calculate the interference range of a single jamming station in a specific terrain, and on this basis, a cyclic iterative method is used to find the optimal layout scheme of distributed jamming suppression. Experimental analysis shows that under experimental conditions, the distributed suppression interference coverage rate of the proposed method is more than 98%, which is obviously better than 74.18% of the traditional high-power single interference source. At the same time, the key suppression interference targets can be further highlighted and multiple suppression interference can be realized by setting red and green zones reasonably.
