Abstract
The spectrum analysis arrangement according to the invention covers a filtering and coupling network comprising a setr of narrow pass band filters, with neighboring center frequencies in steps, whose outputs are coupled one to another through delay devices enabling a resultant signal to be obtained which, at each instant, is the sum of the responses of each filter to the same frequency received at different instants by the analysis receiver fitted with a linearly wobulated oscillator. Application to automatic interception stations in order to obtain precise data quickly on the characteristics of transmission spectra to be identified.
