Radar Cross Section Target Supports, Plastic Materials

摘要

The results of studies into the scattering properties of cellular plastic materials are presented. A mathematical model for scattering from cellular plastics, developed to provide a method of determining the optimum low cross section target support for a given application is also presented. The results of investigations of field perturbations near a Styrofoam surface are described along with cross section measurements using theoretical minimum cross section formula for circular target supports. Structural considerations in the use of Styrofoam as target support material are discussed. Methods for achieving low cross section bonds between pieces of Styrofoam are also discussed. The results of a limited study of the feasibility of air inflated structures as target supports are also presented. (Author)
