This newest edition adds new material to all chapters, especially in mathematical
propagation models and special applications and inverse techniques. It has updated …

The ocean is opaque to electromagnetic radiation and transparent to low frequency sound,
so acoustical methodologies are an important tool for sensing the undersea world …

Synthetic time reversal (STR) is a technique for blind deconvolution of receiving-array
recordings of sound from an unknown source in an unknown multipath environment. It relies …

Acoustic remote sensing of the oceans requires a detailed understanding of the acoustic
forward problem. The results of a shallow-water transmission experiment between a vertical …

This paper investigates the applicability of a ray-based blind deconvolution (RBD) method
for underwater acoustic sources of opportunity such as ships recorded on a receiver array …

This letter describes a ray-based blind deconvolution technique for ocean sound channels
that produces broadband estimates of the source-to-array impulse response and the original …

The Arctic Ocean is undergoing dramatic changes in response to increasing atmospheric
concentrations of greenhouse gases. The 2016–2017 Canada Basin Acoustic Propagation …

Radar clutter in a non-standard atmosphere usually is modeled based on a single grazing
angle at each range. Instead, the angular distribution of incident power can be used to …

Acoustic tomography in a shallow ultrasonic waveguide is demonstrated at the laboratory
scale between two source–receiver arrays. At a 1/1 000 scale, the waveguide represents a …

The array invariant proposed for robust source localization in shallow water is based on the
dispersion characteristics in ideal waveguides. It involves conventional plane-wave …
