Acoustic Ranging System For Multi-Line Towed Acoustic Arrays

Abstract

An acoustic ranging system and method of use is provided that measures the magnitude of the separation of a pair of towed acoustic line arrays at a discrete point along the length of each array. One array acts as the measurement source, while the other array acts as a frequency-shifted echo repeater. The source array incorporates one sonar transmitter and two sonar receivers. The system further includes a configurable frequency shifter that enables one measurement source to make measurements with multiple repeater arrays.
