Paper Abstract

The U.S. Army has collected W-band Radar Cross Section (RCS) data on various rotorcraft landing area clutter types and potential hazards. In collecting this data, two unique features were observed that to our knowledge have been reported in the literature: • When assessing the clutter reflectivity (σo) of long, dry grass in flat terrain with moist soil, a very sharp reduction in the σo value was observed with decreasing EL angle. However, the σo began to rapidly increase when the elevation (EL) angle became less than about 5°. • When assessing the RCS of chain link fencing, the peak response occurred at normal incidence for small EL angles. However, as the EL angle was increased, the off-normal angle for the maximum RCS response shifted by more than 35°. The causes of these seemingly anomalous effects are described in this paper.
