Analyses of Millimeter Wave Radar Low-Angle Ground-Clutter Measurements forEuropean-Like and Desert Environments

摘要

This report describes millimeter wave ground based radar cross sectionmeasurements taken to support the SWOE JTE program over two years. RCS measurements were made on selected ground clutter patches for one month and over another 43-day period at Camp Grayling, MI; and for 47 days at Yuma Proving Ground, AZ. Instruments collected data on meteorological conditions, solar flux, and soil moisture content. A wide range of atmospheric conditions was observed in Grayling over the measurement periods. The conditions in Yuma over the measurement period were relatively stable. In this report, we describe the variations in the ground based measured RCS of different clutter types over time and space for environmental conditions encountered during the three field tests. We have developed and will present an empirical model to describe these variations for the Yuma and Grayling II environments.
