Abstract

This thesis explores the use of periodic open slots as passive antenna scatterers to enhance the radar cross section of a simple target. Two slot geometries are considered, thin rectangular slots and circular slots. Targets are modified with slot arrays of various element size, spacings, numbers, and geometries. These geometries were later backed by a cavity in an attempt to further enhance RCS. Measurements were taken and the results were compared to target baselines, which are nothing more than the unslotted version of the same target. Moment method solutions were also computed for comparisons with measured results. Additionally, an analytical expression for antenna scattering was tested as a means of achieving a fast first order accurate solution for target RCS.
