Radar cross section map for straight wire

Radar cross section (RCS) patterns of a thin straight wire have been computed, and the results have been plotted as constant RCS contours on the frequency-aspect plane for a twenty-to-one frequency range. The resulting map illustrates how the resonant peaks and interference nulls vary simultaneously with frequency and aspect, providing a clear picture of the backscattering behavior and allowing reasonable extrapolation to frequencies considerably higher than those actually calculated.
