A method and device for simultaneously controlling UAV spectrum detection and signal suppression

Abstract

The invention discloses a method and device for simultaneously controlling UAV spectrum detection and signal suppression. The method includes: S1. Executing UAV spectrum detection, when the UAV target is detected, turn to step S2; S2. According to the method of time division multiplexing, it is controlled to switch between different time slots to perform UAV spectrum detection and suppress interference, so that it is divided into multiple time slots to stagger the time to perform UAV spectrum detection and suppress interference; the device includes a More than one UAV spectrum detection equipment, more than one jamming equipment and control equipment. The invention has the advantages of simple implementation, simultaneous work of UAV spectrum detection and signal suppression without mutual influence, good detection and signal suppression performance, and the like.

Description

technical field [0001] The invention relates to the technical field of anti-UAV detection, interference, and control, and in particular to a method and device for simultaneously controlling UAV spectrum detection and signal suppression. Background technique [0002] The working principle of the anti-drone jammer to suppress interference is to use radio waves with the same frequency band as the drone's working frequency and higher power to cover the radio communication between the drone and the remote control, and the satellite positioning signal received by the drone. The working principle of the UAV spectrum detection equipment is to detect the radio communication between the UAV and the remote control, that is, if the UAV spectrum detection equipment and the jammer work at the same time, they will interfere with each other. The signal received by the detection equipment makes it impossible to correctly analyze the signal of the UAV, which affects the spectrum detection com...

Problems solved by technology

However, in the combination of the above-mentioned simple UAV spectrum detection and anti-UAV jammer, the UAV spectrum detection and anti-UAV jamming cannot work at the same time. Once the UAV is detected and the jamming is turned on, the jamming signal It is continuously sent until the interference stops, and the target detection process needs to be suspended during the sending of the interference signal, and the spectrum detection equipment is equivalent to failure, so there will be the following problems:

[0004] 1) After the jamming is turned on, it is no longer possible to obtain the position of the drone in real time, and if the drone is no longer within the effective beam range of the jammer for some reason, the system cannot adjust the direction of the jammer, which will cause the jamming to fail;

[0005] 2) After the jamming is turned on, it is impossible to judge whether the drone has left the armed area. If the drone is successfully driven away, it may be necessary to stop the jamming immediately, but because the system cannot judge whether it has been driven away, it is impossible to stop the jamming in time

[0006] Therefore, it is urgent to provide a method for controlling UAV spectrum detection and signal suppression, so that UAV spectrum detection and signal suppression can be controlled to work at the same time without affecting each other, so as to avoid affecting UAV spectrum detection when jammers are working
