Abstract
System for interconnecting elements of a receiving device of great length, for example a seismic streamer, comprising a plurality of data aquisition apparatuses, each of which is adapted to collect 12 separate signals generated by receiver groups distributed in the different elements. The 12 groups of separate receivers (R.sub.1, R.sub.2 . . . R.sub.12) are regularly distributed in each element (T.sub.1, T.sub.2 . . . ), forming 6 pairs of groups. A first group of each pair (R.sub.1, R.sub.3, R.sub.5) is connected to an input of an acquisition apparatus (B.sub.2). The second group of each pair is connected either to an input of another acquistion apparatus, or to inactive electric connection means (B.sub.1, B.sub.3) adapted to connect in parallel the second and the first groups of each pair. This system can be used in seismic prospecting.
