Interference signal generation device

Abstract

An interference signal generation device provided by the invention is applied to the technical field of communication, and comprises a control module, a signal transceiving module comprising at leastone signal transceiving circuit, a power amplifier and a transmitting antenna, the control module is in communication connection with the signal transceiving module, and the signal transceiving moduleis connected with the transmitting antenna through the power amplifier. The control module analyzes the unmanned aerial vehicle control signal to obtain a frequency hopping sequence and bandwidth ofthe unmanned aerial vehicle control signal, the signal transceiving module generates an initial interference signal with the same frequency as the unmanned aerial vehicle control signal according to the frequency hopping sequence within the bandwidth range, and after the initial interference signal is amplified by the power amplified, an interference signal of which the power is greater than thatof the unmanned aerial vehicle control signal is obtained, and is transmitted by the transmitting antenna. The device can generate an interference signal which has the same frequency and synchronization with an unmanned aerial vehicle control signal and has the power greater than that of the unmanned aerial vehicle control signal to interfere communication between the unmanned aerial vehicle and acontroller.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an interference signal generating device. Background technique [0002] With the popularization of civilian drones, the phenomenon of "black flying" and "random flying" of drones is becoming more and more serious. Drones enter control areas without permission, such as airports, oil depots, troops, and Prisons, etc., pose a great threat to the normal operation and management of the controlled area, and may even become a tool for criminals to carry out illegal activities. [0003] In view of the above situation, how to provide an interference signal generating device to interfere with the UAVs entering the control area, effectively control the UAVs in the control area, and improve the security of the control area has become a technology to be solved by those skilled in the art. one of the problems. Contents of the invention [0004] In view of this, the purpos...
