Abstract
This invention relates to a method and system for distinguishing between displacing targets and a surface of water by transmitting pulses from a transmitter that is submerged in the water, the pulses being reflected and received by a receiver, also submerged in the water. The variations in the distance to the reflecting surface for consecutive pulses are measured and compared with a first value, determined inter alia from the state of the sea, and with another value, determined from the size of the target.
