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.

Arrangement for the determination of the direction and/or distance of

A method for displaying a battle situation under consideration and indication of the movement and position of friendly forces and with the position and motion behavior of targets being derived from angle and distance information, wherein: the display takes place on an electronic display device; one or a plurality of passive bearing systems and/or passive distance measuring systems are provided to furnish angle and distance information of targets which radiate wave energy; position, course and speed are calculated for every target per time interval and displayed as motion vectors; angle and distance information on the targets from given time intervals are used for the display of target paths; markers are associated with the targets resulting from their changes in position and/or the characteristics of signals received from the bearing and/or distance measuring systems and these markers are displayed at the associated target positions; and uncertain measurement regions are calculated from the measuring tolerances of the angle and distance information and displayed for each target.
