Multichannel reception system incorporating a receiver of the superheterodyne type, associated with a spectral band of the analysers instant

摘要

The present invention relates to a reception system sys) (comprising a receiver (rec) of the superheterodyne type coupled to a processing means (rem), the receiver comprising a number n of antennas (v1,.., vn). Said receiver comprises: means for translation (mel11, .. Mel1n), each being able to be translated in the frequency of the signals delivered by the antenna, of an under - frequency band of the range of interest to a restricted frequency band, and multiplexing the signals belonging to said under - frequency band; first n filters - intermediate frequency band (fpn11,.., fp1n), the band width equal to the restricted frequency band, respectively coupled to the output of each translation means, and able to filter the signals translated and multiplexed, a coupling means (cpl) adapted to the n signals filtered so as to deliver the set of n outputs summed signals via. The processing means comprises n other means of translation (mel21,.., mel2n) coupled to the n other filters - intermediate frequency band (fpb21 fpb2n) and frequency band width equal to l, another - same coupled to n spectral analysis (as1,.., asn), all having the same frequency band of the analysis is restricted, of width l, each other means of translation of rank i, i being an integer varying from 1 to n, being able to transpose the signals delivered by the means for coupling with the aid of a translation signal having a frequency tailored to each other means of translation, so that the other filter - intermediate frequency band connected to the output of said other means of translation, that is able to filter the ith under - strip of the total frequency band of width l. n, to which the signals are summed by the coupling means.
