Study on the dynamic adjustment of UAV formation based on purely azimuthal passive positioning

Abstract

In recent years, with the continuous development of unmanned aerial vehicle (UAV) technology, the application of UAV formation flight has also more and more extensive, but the UAV formation is easy to be interfered with by the outside world, which affects the formation. In this paper, we use pure orientation passive positioning, the least squares method to fit the UAV orientation, according to the superior and inferior arc model, cross-positioning, to reduce the UAV formation to emit electromagnetic wave signals to the outside. Firstly, the dynamic adjustment model of UAV formation is established to simulate the dynamic adjustment of two kinds of UAV formation from circular UAV formation to conical UAV formation and from rectangular UAV formation to conical UAV formation, and the simulation results show that the dynamic adjustment scheme of UAV formation under the model has a closer change distance and a shorter change time.
