Countermeasures system for automatically detecting and jamming unmanned planes in all-weather manner

Abstract

The invention discloses a counter system for all-weather automatic detection and interference of unmanned aerial vehicles, comprising a main control computer, a pan-tilt for installing various components, a signal processing module, a control module, a broadband power amplifier, an antenna array and an interference transmission The antenna, the PTZ includes a base, an upper tray, a fork arm and an antenna placement shaft. The interior of the base is equipped with a vertical stepping motor, a radio frequency slip ring, a stepping motor driver, a stepping motor controller, a network switch and a serial port server. The all-weather automatic detection and interference countermeasure system for unmanned aerial vehicles of the present invention can determine whether there are unmanned aerial vehicles in the surrounding airspace by extracting and analyzing the electromagnetic wave signals sent by the unmanned aerial vehicle when it communicates with the remote controller. exist. And signal monitoring mainly relies on signal detection and analysis modules, without manual intervention and participation; it is no longer limited by natural conditions such as night, rain, snow, overcast, haze, etc., so it can achieve all-weather duty.

Description

technical field [0001] The invention relates to the technical field of countermeasure systems for unmanned aerial vehicles, in particular to an all-weather automatic detection and interference countermeasure system for unmanned aerial vehicles. Background technique [0002] The current handheld UAV anti-aircraft gun mainly relies on the visual inspection of the operator to find the flying UAV, and then the operator aims to find, interfere and counter the UAV. First of all, due to the limited detection conditions of human vision (night, rain, snow, cloudy, smog) and the small detection range, it is difficult to find civilian drones 100 meters away; and operators cannot be on duty around the clock. At present, the illegal application of drones has become more and more vigilant: illegal flights at civil aviation airports, illegal stays in the sky above secret-related places to take pictures and videos, etc. Therefore, how to monitor and counter illegal drones has become a hot ...

AI Technical Summary

Problems solved by technology

In the prior art, the discovery of UAVs relies on human eyes, and the size of general UAVs is about 30cm 3 , even in the case of sufficient light, it is difficult for human eyes to detect drones 200m away

And at night or other occasions where visual conditions are limited, the detection distance will also be reduced

The shorter the discovery distance, the shorter the time left for follow-up disposal, which affects the countermeasures against drones

In addition, it is difficult to guarantee 24-hour on-duty and protection of key areas by means of human eye observation and interference methods that must be manually participated.
