Abstract:

A method and apparatus for determining the depth of a marine target relative to the surface of the water which encompasses an analog processing circuit for detecting and analyzing signals reflected respectively from a target and the water surface, a timing and gating circuit respectively responsive to a target echo signal for initiating a timing sequence and to a surface echo signal for terminating the timing sequence, and a depth readout circuit for indicating the depth of the target below the surface at the instant the surface echo signal terminates the timing sequence
