range recorder [′rānj ri‚kȯrd·ər]
(engineering) An item which makes a permanent representation of distance, expressed as range, versus time. (engineering acoustics) A display used in sonar in which a stylus sweeps across a paper moving at a constant rate and chemically treated so that it is darkened by an electrical signal from the stylus; the stylus starts each sweep as a sound pulse is emitted so that the distance along the trace at which the echo signal appears is a measure of the range to the target.
