Abstract

The invention provides a WIFI elimination method and device in unmanned aerial vehicle signal detection and electronic equipment. The method comprises the steps: respectively receiving a first detection signal and a second detection signal at the same time through different receivers; reconstructing a WIFI signal in the first path of detection signal to obtain a reconstructed WIFI signal; estimating the time delay difference between the second path of detection signal and the reconstructed WIFI signal to obtain corresponding time delay difference information; and according to the time delay difference information, the reconstructed WIFI signal and the second path of detection signal, eliminating WIFI interference in the second path of detection signal, and obtaining a target detection signal. According to the invention, WIFI interference in a detection signal is 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...
