Problems solved by technology

In addition, typical jamming devices are configured to emit only single-band jamming EM waves that are limited to intercepting UAVs that can adjust their operating frequency
Therefore, an RF jamming device with only a single-frequency RF emission cannot effectively exclude remotely controlled drones

Abstract

The present invention provides a radio frequency (RF) interference system and method. The RF interference system includes: an RF interference apparatus, for emitting an interferential electromagnetic(EM) wave to an unmanned aerial vehicle (UAV), including an antenna support and at least two antenna modules mounted on the antenna support, the at least two antenna modules being configured to emit RF interference signals with different RF frequencies. The method comprises the steps of: searching and locking an invasion unmanned aerial vehicle; when the invasion unmanned aerial vehicle is locked,opening a power switch to activate the RF interference apparatus; selecting an interference mode, wherein the RF interference apparatus can emit interference RF signals having the same operation frequency as the invasion unmanned aerial vehicle in the selected interference mode to take over the remote control of the invasion unmanned aerial vehicle. The radio frequency (RF) interference system and method can emit the interference RF signals completely covering the working frequency range of the unmanned aerial vehicle to effectively eliminate the unmanned aerial vehicle under different frequencies.

Description

technical field [0001] The present invention relates to a jamming system, in particular to a radio frequency jamming system and method. Background technique [0002] The radio frequency (radio frequency, RF) jamming system can be used to intervene in the remote control of the drone (unmanned aerial vehicle, UAV) or take over the operation of the UAV by emitting RF jamming electromagnetic (interferential electromagnetic, EM) waves, so as to intercept the UAV invasion and approach Military bases such as restricted areas and airport clearance areas. The radio frequency jamming device should be able to emit EM waves at the same radio frequency as the drone's operating frequency to achieve effective jamming. Most remote-controlled drones, such as commercial drones, are generally permitted to operate at 1.5GHz, 2.4GHz, or 5.8GHz, rather than other single bands of the RF spectrum. Furthermore, typical jamming devices are configured to emit only single-band jamming EM waves that a...
