Our primary interests are (1) the statistical models for radar environment such as terrain, ocean, hilly region, forest, atmosphere, ionosphere, and urban region; and (2) relation of the statistical properties of the scattered signals with that of the environment model.
Topics of interest include waves in random media (discrete and continuum models), radiative transfer theory and remote sensing, scattering from randomly rough surfaces, polarimetric scattering, inverse scattering and parameter retrieval from measured data, physics-based models for scattering from terrain and ocean, scattering from media with space-time fluctuations, monostatic and bistatic models for radar clutter, combined random media and rough surface scattering, spectral density of scattering from ocean surfaces, scattering and propagation of radar signals through turbulence in atmosphere and ionosphere, and models for subsurface sensing. Most studies in the literature on these topics are on the derivation of the average scattering coefficients or propagation constants. However, we are interested in more detailed statistics such as probability density function and spectral density of the scattered signals. Often the signals will be of wide bandwidth, so we are interested in the characteristics of scattered signals over a wide range of frequencies. We are also interested in studies on the scattering of targets embedded in complex environment and polarimetric techniques for detecting such targets. The targets may be stationary, mobile, or fluctuating. Of particular interest is the location and imaging of targets embedded in a complex environment.
