Unmanned aerial vehicle navigation decoy device and method based on flight destination prediction

Abstract

The invention provides an unmanned aerial vehicle navigation decoy device and method based on flight destination prediction. The system comprises a main control device, a navigation decoy signal generating and transmitting device, a position measuring device and a remote control signal interference device, the unmanned aerial vehicle is forced to be in an autonomous flight state; a fixed-point navigation deception jamming signal is generated and transmitted to the unmanned aerial vehicle; the unmanned aerial vehicle is forced to change the flight angle after being cheated; calculating destination coordinates of autonomous flight of the unmanned aerial vehicle, and judging whether the unmanned aerial vehicle continuously flies according to the current trajectory according to the deviation between the current actual flight trajectory yaw angle and the expected flight trajectory yaw angle of the unmanned aerial vehicle; and if not, planning a false flight path for trapping the unmanned aerial vehicle, so that the unmanned aerial vehicle flies along the expected flight path as much as possible after being trapped until the unmanned aerial vehicle is forced to land. The problem that theunmanned aerial vehicle is out of control due to the fact that decoy signal parameters cannot be dynamically adjusted according to the flight path of the unmanned aerial vehicle in the prior art canbe solved.

Description

technical field [0001] The invention relates to a UAV navigation decoy device and method based on flight destination prediction, and belongs to the technical field of "low, slow and small" UAV defense and navigation warfare. Background technique [0002] With the rapid development of drone technology and the popularization of applications, various safety accidents and illegal and criminal activities related to it emerge in an endless stream. At present, common UAV defense and control methods include flexible net capture, laser interception, microwave damage, and radio frequency suppression. Among them, radio frequency suppression has been widely used due to its advantages such as long distance, mild means, and flexible deployment. However, most of the above-mentioned methods are passive drive-off and damage-type defensive measures, which are difficult to realize the active control of UAV flight trajectory and forced landing area, and can easily cause collateral damage to the...
