Abstract

Enhanced backscatter effects associated with the mean intensity and scintillation index for a monostatic propagation channel through atmospheric turbulence are analyzed for two spectral models of refractive-index fluctuations. The analysis presented here shows that using a more physically realistic modified spectrum with inner and outer scale parameters as well as a high-wave-number rise (bump) can lead to significantly different results than those predicted by the idealized Kolmogorov power law spectrum. The target models used in this analysis include a smooth target finite mirror, glint target finite retroreflector, and a rough surface target (Lambert surface). The general method of analysis is based on weak fluctuation theory.
