Arrangement for the determination of the direction and/or distance of objects by means of water-borne sound waves |
摘要 |
The system is for determining the direction and/or distance of objects and, especially of watercrafts, by means of water-borne sound waves transmitted from the ship to a torpedo, for example. The system includes a cathode ray tube located on the ship for displaying sectors of interest, at least one storage means at the torpedo for storage and delivery of sound location data and being connected to a length of wire for transmitting stored location data over the wire to the ship, a controllable threshold discriminator connected to the storage means, and means for limiting the frequency bandwidth of data signals transmitted over the communication wire to an order of magnitude of 500 Hz.
