Submarine simulating sonar beacon










Image Number 10 for United States Patent #4198703.

1. In a submarine simulation sonar beacon adapted for predetermined maneuing under water, a hull having a forward and an aft transducer for receiving an acoustical signal within said water, means disposed in said hull connected to said forward and aft transducers for comparing the time relationship of arrival of said acoustical signal thereat, means coupled to said comparing means for generating an output signal having a characteristic which is a function of said time relationship, means coupled to said generating means for amplitude and highlight modulation of said output signal, and transmitting transducer means mounted on said hull and coupled to said last mentioned means for broadcasting said modulated signal through said water.
