Abstract:

This report presents a complete treatment of the second-order statistics of intensity under conditions of strong scattering. A three-dimensional powerlaw striation model is used in the analysis. For completeness, the special forms for a strictly two-dimensional medium are also derived. Asymptotic formulas for the fade coherence time are derived. Simple asymptotic results can be derived only for three-dimensional spectral indices less than 4. However, naturally occurring striations seem to fall in this range, and the simple formulas are generally applicable.
