Problems solved by technology

Due to its small size, the body is made of very little metal, its radar reflection cross-sectional area (RCS) is very small, and its flight altitude is very low, so it is difficult to find and identify drone targets using conventional mine detection methods

Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The invention discloses a UAV early warning management and control method. The method is based on the UAV self-transmitting signal, by setting a plurality of signal receiving stations to receive and process the signal, extracting target feature information and identifying the UAV target, and estimating each receiving station Based on the signal parameters, the positioning equation is constructed based on the relationship between the signal parameters and the target position, and the target position is obtained by solving the positioning equation. The tracking filter technology is used to further suppress the positioning error, and a more accurate target position and speed can be obtained, and the target is displayed on the electronic map in real time. Based on information such as position and movement trajectory, illegal t...

Abstract

The invention relates to unmanned warning control techniques and discloses an unmanned aerial vehicle warning control method and system. An unmanned aerial vehicle may transmit a signal out constantly during flight; based on the signal transmitted by the unmanned aerial vehicle itself, multiple receiving stations are provided, and the signal transmitted by the unmanned aerial vehicle is received by a signal receiving unit; an acquisition processing unit acquires the signal, processes the signal, recognizes the signal, extracts features and estimates parameters; a positioning tracking unit positions and tracks the unmanned aerial vehicle, extracts location and acceleration information of a target, and transmits to a warning monitoring unit; the warning monitoring unit predicts a location of next moment according to the current location and speed of the target, automatically recognizes whether the target is illegal or not based on the feature information of the target, automatically triggers warning if it is detected that the illegal unmanned aerial vehicle invade a flight 'restricted zone', and transmits shooting guide information to an expelling shooting unit, the expelling shooting unit shoots the illegal target, expels or shoots off the target, and accordingly warning monitoring and control are provided for the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of UAV early warning management and control, in particular to a method and system for UAV early warning management and control based on signals emitted by UAVs. Background technique [0002] In recent years, as the development and production threshold of small and medium-sized drones has been greatly lowered, a large number of light and small civilian drones have entered the market and become "high-end toys" in the hands of enthusiasts. Their commercial value has also continued to expand and are widely used in Aerial photography surveying and mapping, pipeline inspection, forest fire prevention, agricultural and forestry operations, logistics and catering and many other fields. However, due to the incomplete laws and regulations and industry standards for the management of civilian drones in my country, the drone market has a greater degree of freedom in development, and the quality of products is uneven. Sa...
