Embodiment Construction
[0026] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0027] When UAVs fly in formation to perform missions, they not only need to solve the necessary communication, data fusion, flight control and other technologies during the flight of a single UAV, but also need to solve problems such as formation maintenance, collision avoidance and obstacle avoidance, and track planning. In this paper, it is assumed that the aircraft in the UAV dense cluster can exchange Bluetooth short-distance information with each other without barriers.
[0028] 1. Electromagnetic vector sensor receiving signal model
[0029] The direction of electromagnetic wave signal propagation is as figure 1 As shown, in the geodetic coordinate system, the parameter of the direction of arrival of the electromagnetic wave space Represents azimuth angle and elevation angle respectively, -π / 2≤θ≤π / 2, Then the arrival vector is The pol...
