Abstract
Abstract A decoy missile is constructed with a centrally located dielectric region to establish electrically isolated forward and rearward vehicle sections. Various antenna arrangements are utilized to provide electromagnetic wave backscatter control. The antenna arrangements comprise combinations of laterally disposed coaxial cable stubs and peripherally disposed segmented ring antennas.
