Abstract

An embodiment of the present invention provides a passive UAV positioning method and server, the method includes: receiving spectrum information sent by at least 4 radio detectors; the spectrum information is sent by the radio detector based on the received UAV The communication signal is obtained by time-frequency conversion; based on the spectrum information, determine the time difference between the two radio detectors receiving the same communication signal sent by the UAV; The time difference of the same communication signal sent by the UAV is determined to determine the three-dimensional position information of the UAV. In this way, the detection and positioning of passive drones can be realized, without electromagnetic pollution to the environment, high positioning accuracy, no detection blind spots, and high environmental adaptability, which can be used in complex electromagnetic environments in cities.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a passive unmanned aerial vehicle positioning method and server. Background technique [0002] With the rapid development and popularization of drones, the technical threshold for consumer drones is not high. A set of open source programs can support the takeoff and landing of aircraft. Anyone can use open source programs to build a drone platform . While UAVs are widely used in different fields, their safety hazards are gradually emerging. UAVs are used by users who have no professional training, to satisfy personal interests, and have no awareness of flight laws and regulations, as well as lawbreakers. It poses a huge threat to public privacy, property, and life safety. In view of the current lack of control over unmanned aerial vehicles, there is an urgent need for a practical and low-cost method and device for detecting and positioning unmanned aerial vehic...
