Abstract : The reflection of quasimonochromatic radiation from random discontinuities in a long transmission line is analyzed using the theory of partial coherence. Graphical probability density functions for the power reflection coefficient at the input to the line are obtained as a function of the spectral characteristics of the illuminating signal, the properties of the propagation medium, and the distribution of the scatterers. Theoretical expressions for the mean and variance of the power reflection coefficient are also obtained. The mean, variance, and probability density functions for the power reflection coefficient obtained experimentally are compared with the theoretical results and show good agreement. (Author)
