Airport terminal area unmanned aerial vehicle early warning and countermeasure system and method

Abstract

The present invention relates to an airport terminal area unmanned aerial vehicle early warning and countermeasure system and method. The system includes an unmanned aerial vehicle early warning subsystem and an unmanned aerial vehicle countermeasure subsystem; external radiation source radars are networked so as to form the unmanned aerial vehicle early warning subsystem; the unmanned aerial vehicle early warning subsystem is used for the surveillance of and early warning against the intrusion of unmanned aerial vehicles; and the unmanned aerial vehicle countermeasure subsystem includes a low-altitude surveillance radar, a photoelectric recognition subsystem and an interference subsystem, wherein the low-altitude surveillance radar is used for accurately detecting and tracking a suspicious target reported by the external radiation sources, the photoelectric recognition subsystem performs imaging analysis on the tracked suspicious target to confirm whether the suspicious target is an invading unmanned aerial vehicle, and the interference subsystem performs directional frequency interference on the confirmed invading unmanned aerial vehicle or destroys the confirmed invading unmanned aerial vehicle. The airport terminal area unmanned aerial vehicle early warning and countermeasure system and method are unmanned aerial vehicle countermeasure comprehensive solutions which are provided according to the operation rules and safety supervision of civil aviation terminal regions. The system and method have the advantages of wide coverage, low frequency occupation rate, easiness ininstallation and construction, low cost and the like.

Description

technical field [0001] The invention relates to the fields of low-altitude surveillance technology and UAV supervision, in particular to a UAV early warning and countermeasure system and method in a terminal area of ​​a civil aviation airport. Background technique [0002] With the rapid development of the drone industry, consumer drones used for personal entertainment have seen a blowout growth. However, the supervision of the drone industry is not clear enough, the threshold of the industry is low, and various random and black flights emerge in an endless stream. According to the executive secretary-general of the Chinese Aircraft Owners and Pilots Association (AOPA) According to Ke Yubao, there are currently at least 20,000 drones in China that are basically in the "black flight" state. This unsupervised state of black flights has led to frequent incidents of drones breaking into civil aviation airports or air routes, bringing huge security risks to flight operations. A...

[0008] (3) Complex equipment installation approval

[0010] Most consumer drones fly at low altitudes, slow speeds, and are small in size. The existing anti-UAV systems usually only have a range of 3 to 5 kilometers for UAVs. Therefore, the existing anti-UAV systems It is often only applicable to UAV countermeasures in specific areas in a small range

To achieve UAV countermeasures in such a large area as the airport terminal area, there are disadvantages such as a large amount of equipment, complicated installation and location selection, high cost, and the need to apply for new electromagnetic wave frequencies. machine system reason
