Abstract

The embodiment of the invention provides a ground station, and the ground station comprises a main control unit, unmanned aerial vehicle image transmission and a display. The main control unit obtainsa frequency sweeping instruction of a specified frequency band, sends the frequency sweeping instruction of the specified frequency band to an unmanned aerial vehicle image transmission unit, receives the frequency spectrum density transmitted by the unmanned aerial vehicle image transmission, and transmitts the frequency spectrum density to a display, the frequency spectrum density comprising: the frequency spectrum density of each frequency point in the specified frequency band; the unmanned aerial vehicle image transmission is used for receiving a frequency sweeping instruction of the specified frequency band, performing frequency domain conversion on the time domain signal in the specified frequency band to obtain a frequency domain signal of each frequency point in the specified frequency band, processing the frequency domain signal by using the obtained signal energy value of the specified frequency band to obtain frequency spectrum density, and sending the frequency spectrum density to the main control unit; wherein the frequency domain signal is the frequency spectrum characteristic of each frequency point in the specified frequency band; and the display is used for displaying the received frequency spectrum density.

Description

technical field [0001] The invention relates to the technical field of radio frequency spectrum analysis, in particular to a ground station. Background technique [0002] At present, both UAV flight and UAV image transmission require a stable wireless environment, and the actual wireless environment may have relatively serious wireless interference. In the presence of wireless interference, the image quality of UAV image transmission deteriorates, and even image loss occurs. If it is more serious, the UAV may also lose connection. Therefore, it is necessary to detect wireless interference in the wireless environment to determine the current Interference conditions in a wireless environment. [0003] The professional equipment to detect the current wireless environment is a spectrum analyzer. The steps to use the spectrum analyzer to detect wireless signals in the wireless environment are as follows: [0004] First, the spectrum analyzer obtains the wireless signals of each...
