Non-Cooperative Positioning Technology Based on AOA Information Fusion

Most non-cooperative positioning algorithms require different measurements, and some in some cases only have the azimuth information of the target. In order to solve this problem, a pure azimuth intersection method and a hierarchical clustering method based on abbreviated conditions were proposed to realize non-cooperative positioning. The pure azimuth intersection positioning algorithm quickly analyzes the number and location of redundant targets from the obtained azimuth information. The hierarchical clustering method removes a large amount of redundancy, and finally determines the communication relationship of the prediction location, so as to determine the importance of communication between targets. The simulation results show that the pure azimuth intersection algorithm has higher positioning accuracy than the traditional intersection algorithm.
