Abstract

The invention provides a WIFI elimination method and device in unmanned aerial vehicle signal detection and electronic equipment, and the method comprises the steps: obtaining two paths of identical detection signals which are a first path of detection signal and a second path of detection signal respectively; reconstructing a WIFI signal in the first path of detection signal to obtain a reconstructed WIFI signal; and performing synchronous subtraction on the reconstructed WIFI signal and the second path of detection signal to obtain a target detection signal with WIFI interference eliminated.According to the invention, WIFI interference energy in a detection signal can be effectively eliminated, and an unmanned aerial vehicle signal can be completely and effectively reserved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a WIFI elimination method, device and electronic equipment in unmanned aerial vehicle signal detection. Background technique [0002] With the rapid development of drone technology, more and more ordinary users start to use drones. Although drones have brought convenience to ordinary users in terms of video shooting and lightweight item transportation, it is precisely because of this convenience and a large number of promotions that it has caused difficulties in supervision. It has increasingly become one of the unstable factors of social public security, and some have even caused serious consequences. In order to be suitable for the supervision of UAVs, it is necessary to detect UAV signals through corresponding technical means. [0003] In the existing related technologies, most of the UAVs are controlled by wireless communication, that is, the UAV and the control end c...
