Radio monitoring station with a spectrally analysis arrangement

摘要

The present invention relates to devices for spectral analysis. / p & & p & the device according to the invention relates to a set of filtering and of coupling comprising a set of filters - band narrow, of the adjacent central frequencies staggered, whose outputs are interconnected through the delay devices making it possible to obtain a resulting signal which is, at each instant, the sum of the responses of each filter to a same frequency received at different times by the receiver of the analysis is equipped with an oscillator wobbulated linearly. / p & & p & the application of the stations of interception automatically in order to rapidly obtain accurate information on the characteristics of the spectra of the transmissions to identify.
