An experiment conducted in the Mediterranean Sea in April 1996 demonstrated that a time-reversal
mirror (or phase conjugate array) can be implemented to spatially and temporally …

In July 1999, an at-sea experiment to measure the focus of a 3.5-kHz centered time-reversal
mirror (TRM) was conducted in three different environments: an absorptive bottom, a …

This paper describes estimation of low‐altitude atmospheric refractivity from radar sea clutter
observations. The vertical structure of the refractive environment is modeled using five …

Non-standard radio wave propagation in the atmosphere is caused by anomalous changes
of the atmospheric refractivity index. In recent years, refractivity from clutter (RFC) has been …

During the July 2003 acoustic communications experiment conducted in 100 m deep water
off the western side of Kauai, Hawaii, a 10 s binary phase shift keying signal with a symbol …

We address the problem of tracking the spatial and temporal lower atmospheric variations in
maritime environments. The evolution of the range and height-dependent index of refraction …

The multi-snapshot, multi-frequency sparse Bayesian learning (SBL) processor is derived
and its performance compared to the Bartlett, minimum variance distortionless response, and …

Simultaneous measurements of infrasonic (0.5–20 Hz) acoustic particle velocity and acoustic
pressure made by the Marine Physical Laboratory’s set of freely drifting Swallow floats are …

This paper describes a Markov chain Monte Carlo (MCMC) sampling approach for the
estimation of not only the radio refractivity profiles from radar clutter but also the uncertainties in …

Matched field processing is a generalized beamforming method that matches received array
data to a dictionary of replica vectors in order to locate one or more sources. Its solution set …
