The statistical characteristics of the response of an array of hydrophones to a moving narrow‐band acoustic source in an ocean waveguide are investigated. The discrete Fourier transform of a solution of the wave equation with a moving source is cal

Hyperspectral data are often modeled using either a linear mixture or a statistical classification approach. The linear mixture model describes each spectral vector as a constrained linear combination of end-member spectra, whereas the classification

Hyperspectral images may be collected in tens to hundreds of spectral bands having band widths on the order of 1-10 nanometers. Principal component (PC), maximum-noise-fraction (MNF), and vector quantization (VQ) transforms are used for dimension red

Multispectral and hyperspectral sensors are being used for remote sensing and imaging of ocean waters. Many applications require the compression of hyperspectral data to achieve real-time transmission or exploitation. Hyperspectral data compression o

Sea clutter amplitude is often modeled as a compound random variable Z equals AX, where A is a positive valued random variable and X has a Rayleigh distribution. The K, class A, and discrete Rayleigh mixture distributions can be derived from these as
