Miniature unmanned aerial vehicle low-altitude hidden flight method

Abstract

The invention discloses a miniature unmanned aerial vehicle low-altitude hidden flight method. The method sequentially comprises the following steps of performing horizontal arc flying: taking a dangerous target as a circle center, the distance between the dangerous target and the unmanned aerial vehicle as a radius, and the three-point collinear position of the hidden background, the unmanned aerial vehicle and the dangerous target as the end point to serve as a horizontal arc-shaped track, wherein the unmanned aerial vehicle flies along the horizontal arc-shaped track or the corresponding chord; performing steering lifting flying: the unmanned aerial vehicle flies up to be higher than the dangerous target; and performing continuous hidden flying: the unmanned aerial vehicle flies linearly towards the direction of the dangerous target, flies to the rear of the dangerous target, and then continuously flies to be far away from the dangerous target. According to the method, the flight state is changed by finding the hidden background, the sight tracking of the dangerous target can be effectively avoided, so that the micro unmanned aerial vehicle can be protected in a long-distance task execution process.

Description

technical field [0001] The invention relates to the technical field of a micro-UAV flight intelligent control system, in particular to a low-altitude concealed flight method for a micro-UAV. Background technique [0002] With the continuous development of remote-controlled aircraft with real-time image acquisition and transmission functions, namely unmanned aerial vehicles, its volume can be made more and more miniaturized, and its flight range is also increasing. and complex space environment, on the other hand, its flight operations have better privacy. However, for some micro-UAVs with a large flight range, the place where the mission is performed is far away from the operator or the operation base, so the operator or the operation base cannot directly provide protection for the micro-UAV. Long-distance missions may be monitored and then captured or attacked. If an effective method of protecting micro-drones cannot be provided, long-distance missions will be difficult to...

However, for some micro-UAVs with a large flight range, the place where the mission is performed is far away from the operator or the operation base, so the operator or the operation base cannot directly provide protection for the micro-UAV. Long-distance missions may be monitored and then captured or attacked. If an effective method of protecting micro-drones cannot be provided, long-distance missions will be difficult to carry out

[0003] Miniature multi-rotor UAVs usually fly at a low altitude, and the distance from the ground is usually between 1 meter and 5 meters. Therefore, micro multi-rotor UAVs flying at low altitudes are more vulnerable to attacks by people who are empty-handed or holding simple appliances or capture; in addition, due to the limited flight speed of the miniature multi-rotor UAV, it is also possible to be chased or chased by flying directly away from threatening personnel
