Tables of Radar Cross Sections of Hemispheres on Perfectly Conducting Ground Planes

摘要

It is proposed that a hemisphere be used as the standard target when radar cross section measurements must be made of a target on or near a ground plane. These tables enable the radar cross section of any hemisphere whose radius is in the range 0.1 to 10.0 wavelengths to be determined for angles of observation up to 30 degrees from the horizontal. Asymptotic expressions are presented for hemispheres outside the size range of the tables.
