This paper describes a simple approach for inferring the depth and track of a sound source at short ranges by inversion of acoustic field data at a set of sea bottom hydrophones. At short ranges, the acoustic field consists of a dominant Lloyd mirror (LM) signal from the direct and surface-reflected ray paths and a series of bottom-reflected paths that modulate the LM signal. A computationally efficient...
A short-range, shallow-water transmission loss experiment was conducted in the South Lincoln Sea, under an irregular rough ice canopy. A barrel-stave source was used to transmit 800-Hz tonal signals at depths of 10 and 30 m. The signals were received on a four-element vertical line array distributed over the 65-m water depth. To support the transmission loss measurements, a bottom loss experiment...
