ABSTRACT:
A digital device for forming spatial channels for sonar equipment having a sonar transducer array including N sensors. Signals from the N sensors are sampled and multiplexed in series. A memory having a plurality of memory blocks stores the samples of the sensor signals. The memory blocks may conveniently be divided into two groups. The group acquires samples during a time interval T.sub.c from the N multiplexed signals. Each memory block thus stores P groups of N samples. The samples stored in one memory block are then transferred to the next block. Finally, the samples stored in each memory block of the first group are transferred into the corresponding memory block of the second group in which the delayed samples are read and summed to deliver simultaneously Q time samples of the same spatial channel.
