Abstract

A self-guidance system for submarine vehicles containing a parametric sonar including preformed channel, transmission device and, in each channel, two beams at the primary frequencies formed simultaneously. Reception takes place with preformed beams at the primary and the secondary frequencies followed by a filter giving frequential channels. An echo comparator receives the signals at the primary and secondary frequencies and enables interference echoes from decoys in particular to be eliminated and the rudders to be controlled.
