Embodiment Construction
[0015] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] The present invention provides a high-efficiency and low-complexity communication method between a UAV and a ground measurement and control station, which adopts electronically assisted multi-beam antenna technology, and captures the UAV's initial position and real-time attitude information captured by the UAV's GPS and sensors. The airborne multi-beam antenna is aligned with the ground measurement and control station at the first level, and then the beam with the best link status is selected for communication according to the received signal strength of each beam. The present invention upgrades the traditional communication method to an electronically assisted communication method based on sensors, and achieves the effect of improving the beam precision. The multi-beam antenna system is used for beam selectio...

The invention provides an electronic assistant unmanned aerial vehicle communication method based on a multi-beam antenna, and belongs to the technical field of an unmanned aerial vehicle. According to the invention, an electronic assistant multi-beam antenna communication scheme is adopted, a movement displacement and an attitude variation of the unmanned aerial vehicle are calculated by acquiring an initial position and a real-time attitude of the unmanned aerial vehicle, which are captured by an onboard GPS and an attitude sensor, and relative positions of the unmanned aerial vehicle and aground measurement and control station and a beam emission angle of the onboard antenna of the unmanned aerial vehicle are determined. According to the calculated beam emission angle and relative positions, a beam emission angle from the onboard antenna to the ground measurement and control station is regulated, so that the onboard multi-beam antenna is always aligned with the ground measurement and control station, thereby completing primary alignment of the antenna. Finally, according to intensity of each beam receiving signal, a beam with an optimal link state is selected to carry out communication. According to the invention, signal transceiving intensity is improved by the low-complexity method, efficient communication between the unmanned aerial vehicle and the ground measurement andcontrol station is completed, and accuracy of antenna alignment is improved.
Description
technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, relates to unmanned aerial vehicle measurement and control communication technology, and in particular relates to an electronically assisted unmanned aerial vehicle communication method based on a multi-beam antenna. Background technique [0002] In the field of UAV communication measurement and control, how to realize long-distance, low-power communication is a difficult problem for UAV efficient communication. At present, ground servo tracking antenna equipment and airborne single antenna system are mainly used to realize UAV measurement and control communication. However, due to the low gain and poor directional communication capability of the airborne single-antenna system, long-distance UAV measurement and control and efficient communication cannot be realized. [0003] The existing airborne single-antenna system has the characteristics of light weight and low power consump...
