The invention relates to the technical field of
wireless communication
signal analysis, in particular to a
channelized high-precision real-time
spectral analysis method and a
channelized high-precision real-time
spectral analysis system. According to the
channelized high-precision real-time
spectral analysis method, radio-frequency signals are collected through reception, high-frequency signals are converted into middle-frequency signals and then subjected to channelized
decomposition, and grouped low-pass filtering treatment is performed to display
frequency spectrum information. The channelized high-precision real-time spectral
analysis method and the channelized high-precision real-time spectral analysis
system have the advantages that the analysis bandwidth is wide,
frequency resolution is high, procedure codes are concise, the
data processing structure is efficient, and a universal
frequency spectrum analysis platform is easy to set up; the method and the
system are applicable tofrequency spectrum detection and management of radios for civil use, and suitable for design demand of the military fields such as
radar and electronic countermeasures, and have high significance in development of people's
livelihood, stabilization of national defense and the like.
