Abstract

The invention discloses a radio-frequency spectrum monitoring device which comprises a monitoring antenna, a monitoring receiver and a spectral analysis device. The radio-frequency spectrum monitoring device further comprises a data flow divider, a signal amplifier and a signal filter, wherein the data flow divider is arranged between the monitoring receiver and the spectral analysis device, the signal amplifier is arranged between the monitoring antenna and the monitoring receiver and the signal filter is arranged between the signal amplifier and the monitoring receiver and used for filtering amplified spectral data. The spectral analysis device analyzes the spectral data received by the monitoring receiver according to the preset analysis bandwidth and the center frequency, and therefore the signal scanning spectral range is obtained. According to the scanning spectral range and a preset threshold value, whether a signal frequency point exceeds the threshold value or not is determined; when the signal frequency point exceeds the threshold value, it is determined that interference is caused, and therefore the frequency band where the frequency point is located is removed according to the set interference removal bandwidth; when the signal frequency point is within the threshold value range, the frequency band meeting the requirement is obtained according to the set frequency bandwidth.

Description

technical field [0001] The invention relates to the technical field of radio spectrum analysis, in particular to a radio spectrum monitoring device. Background technique [0002] In the complex electromagnetic environment of aerospace TT&C, UAV TT&C and modern radio TT&C, due to the dense distribution of spectrum resources, the system cannot effectively avoid the radio that causes interference in a complex environment. [0003] At the same time, due to the large size of the equipment in the prior art, it is inconvenient to carry, and the user experience is poor. Contents of the invention [0004] The embodiment of the present invention provides a radio frequency spectrum monitoring device, which solves the technical problem in the prior art that in the complex electromagnetic wave environment, the radio that causes interference cannot be effectively avoided, and then realizes that the radio that can effectively detect interference The technical effect of evasion.
