Bearings-Only Passive Localization in Unmanned Aerial Vehicle Formation Based on Mathematical Model

In recent years, with the improvement of electronic technology, the maturity of satellite positioning system and the emergence of new UAVs, UAVs have entered a stage of rapid development. In order to ensure the concealment of UAVs and avoid external interference as much as possible, passive location and tracking system has gradually become a research hotspot when UAVs are flying in formation. The method of passive location has strong anti-interference ability and good concealment, which is a bridge between positioning technology and algorithm performance analysis. In this paper, aiming at the problem of how to maintain the formation of UAV cluster in the process of formation flight, the positioning coordinates of UAV are obtained by optimizing the particle swarm optimization algorithm, and the appropriate positioning model is constructed by using the bearing-only passive positioning algorithm. The position adjustment scheme of UAV is studied and extended to other formation scenarios.
