Radar Clutter Via Ray Methods
Abstract
In a recent study, radar clutter results calculated via waveguide methods were compared with Tappert's backscatter results generated by using parabolic equation and Monte Carlo methods. For the geometries and environments considered, the waveguide results generally broke down for ranges less than about 8 kilometers. In this study, ray methods, along with results of first order scatter theory, are used to calculate clutter for ranges applicable to direct illumination. The latter includes those close in ranges not accessible via waveguide methods. Ray theory comparisons with Tappert's results and waveguide results are given at 9.6 gigahertzs for the standard atmosphere, and for 14 and 28 meters evaporation ducts. Results apply to wind speeds of 10, 20, 30, and 40 knots at a transmitter altitude of 25 meters. Keywords: Waveguide methods, Radar clutter, Active and passive radar detection and equipment, Ray methods.
