Miniature, low power, generic Doppler sonar

Abstract

The Oceanographic Systems Laboratory at Woods Hole Oceanographic Institution has developed a small, low power, single-axis, range-gated pulse-coherent Doppler sonar, that is primarily intended for boundary layer turbulence studies. This instrument is composed of a receiver-transmitter, a 24MHz analog-to-digital converter, a down converter, and a low power Digital Signal Processor (DSP). The system is capable of autonomous operation from a variety of stationary platforms, such as buoys, moorings, and bottom frames, and small mobile platforms, including gliders, profilers, towed bodies and autonomous underwater vehicles (AUVs).
