When a harmonic wave train traveling in an elastic rod strikes its interface with a contained fluid column of the same radius, some of the energy is transmitted to the fluid and the rest is reflected back down the rod. In the process, elastic energy

The maximum likelihood bearing estimator has been simulated on a computer and has been used to examine the effects on performance of both environmentally imposed conditions and system parameters. The imposed conditions include source spectra, ambient

Drift of the standing wave pattern in an acoustic doppler intrusion detection system in a confined space is compensated by adjusting the relative radiating and receiving positions of the radiator and receiver transducers, respectively, either mechani

A short‐based planar array using omnidirectional microphones was chosen for bearing estimation as the result of the Cramer‐Rap bound analysis done. The acoustic wavefront traversing the horizontal array is assumed to be a plane wave. Information

The utility of a coaxial electret cable transducer as a hydrophone at shallow depths (low hydrostatic pressure) is extended for operation at substantially greater depths (high hydrostatic pressure) by the combination of the electret with a polymer ma
