Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a pilot positioning system and method of a black flying unmanned aerial vehicle. Background technique [0002] In recent years, with the continuous development of drone technology, the threshold is also falling, and there are more and more drone manufacturers, because consumer drones have a low threshold for operating and are oriented to the mass market. More and more users do not have any standardized training and do not understand how to avoid drone flight failures, which brings a series of safety hazards; and the use of criminals poses a huge threat to public privacy, property, and safety. Therefore, it is essential to control black flying drones.

More and more users do not have any standardized training and do not understand how to avoid drone flight failures, which brings a series of safety hazards; and the use of criminals poses a huge threat to public privacy, property, and safety. Therefore, it is essential to control black flying drones

[0003] At present, the commonly used UAV countermeasures include radar or radio detection, and the radar system cannot detect low, slow, small static targets or slow moving targets; the power is large, and the high-frequency signals are emitted to generate strong electromagnetic radiation; There are many blind spots, such as short-distance blind spots, headspace blind spots, and low-altitude blind spots; and for the environment where the control terminal of the drone (ie, the pilot) is located, whether it is a relatively high roof or a walkable road radar is It is not searchable, so radar detection of pilots cannot be achieved

For radio detection, the position of the UAV is located by the downlink signal, and the position of the pilot is located by the uplink signal. Due to the small data volume, narrow bandwidth, and poor continuity of the uplink signal, it is difficult to analyze other radio signals in a mixed environment, and the pilot needs to be in an open space. The position of the pilot can only be analyzed in an unobstructed environment. Assuming that the pilot is controlling the UAV outside the blind zone of radio detection or the effective defense zone, the radio detection can only receive weak and incomplete uplink signals from the remote control. Then the conditions cannot be analyzed, so the position of the pilot cannot be located
