Statistical Properties of Bistatic Clutter Echoes.

Abstract

In this report we present statistical results of bistatic terrain reflectivity measurements. A new technique for estimating statistical properties from limited data sets was used to examine underlying temporal probability density functions (PDFs) and correlation properties of echoes from several clutter range resolution bins. The case of locally vertically incident-vertically received signal polarization is reported for a single bistatic geometry. The terrain in the experiment consisted primarily of early-development deciduous trees. 10-15 feet high and brush approximately 8 feet high. The measurement system was a high resolution instrumentation radar operating at 3.2 GHz. Results from the estimation algorithm showed that there were small groups of contiguous clutter cells where the members within the group could be described by the same family of PDFs. while other PDF families would best describe neighboring clutter cell groups. Algorithm results for all tested clutter cells showed that the high-resolution, bistatic echoes were non-Rayleigh distributed.
