Statistical Analysis of High Resolution spatially correlated Land Clutter at Millimeterwave Frequencies

Inhalt:
The analysis of the reflectivity values of polarimetric ground clutter has shown that for many clutter types there is a considerable amount of spatial correlation depending on the type of clutter. In particular we consider two-dimensional (m1,m2)-dependent processes. This raises the question, which consequences these dependences have for the estimation of parameters. Therefore, a central limit theorem for (m1,m2)-dependent processes is necessary. The central limit theorem for the means of (m1,m2)-dependent processes provides a probability density function with which the histogram of several sample means can be compared.
