Patent ID: 8755367

Claim:
A reception system comprising a receiver of superheterodyne type coupled to a processing means, the receiver comprising a number N of antennas, each being able to pick up signals representative of incident waves over a given span of interest and to deliver corresponding signals, N being an integer, said receiver comprising: N translation means, each being able: to frequency translate signals delivered by the antenna considered, from a frequency sub-band of the span of interest to a restricted frequency band, and to frequency multiplex the signals belonging to said frequency sub-band; N first identical intermediate frequency bandpass filters, of bandwidth equal to said restricted frequency band, respectively coupled at the output of each translation means, and able to filter the translated and multiplexed signals; and a coupling means able to sum the N filtered signals so as to deliver the set of summed signals via N outputs; wherein the processing means comprises N other translation means coupled to N other bandpass filters of mutually identical intermediate frequency different from the intermediate frequencies of the N first bandpass filters and of frequency bandwidth equal to L, themselves coupled to N spectral analyzers, all having the same restricted analysis frequency band of width L; wherein each of the other translation means of rank i, i being an integer varying from 1 to N, is able to transpose the signals delivered by the coupling means with the aid of a translation signal having a frequency adapted to each other translation means, in such a way that the other intermediate frequency bandpass filter connected at the output of said other translation means, is able to filter the i th sub-band of the total frequency band of width L·N, to which the signals summed by the coupling means belong.
