Bearings only passive location of UAV in formation flight based on computer simulation

Abstract

Azimuth-only target location and tracking based on image vision is a passive target location method, which has become a research hotspot of target tracking at present. Aiming at the problem of bearings only passive location of UAV, this paper establishes a geometric location model of UAV bearings, and finally realizes bearings only passive location of UAV. This paper first analyzes the data and establishes a data flow chart. By defining the position of the UAV, the positioning model of the UAV with a passive receiving signal is established. GeoGebra is used to visualize the data. This paper can determine that there are five positioning models of UAV position deviation, namely, inside and outside the circumference, left and right of the circumference, without deviation. Then, by adjusting the position of the received signal source UAV, this paper constructs a visual mathematical model by classification, discussion, arrangement, and combination, and determines that two more UAVs are needed to achieve effective positioning of the UAV. At last, GeoGebra is used to make assumptions about the position adjustment of the UAV, and Matlab is used to simulate it to obtain an ideal state model.
