Non-Specular Radar Cross Section Study
Abstract
The broad objective of this research is to develop techniques to reduce non-specular scattering from objects of interest to the Air Force. The major tools used thus far in the investigations have been two-dimensional computer programs which solve the integral equations for a surface impedance boundary condition and for a thin resistive sheet placed near a conducting obstacle. The existing programs have proven valuable, but the research requirements have now outstripped their capabilities and more inclusive programs are required. The main thrust of this Interim Report is upon the development of the integral equations necessary for the contribution of more comprehensive programs, but for the sake of completeness, the equations for the existing programs are also derived as a matter of course. Of considerable importance is the treatment of 'magnetic' resistive sheets in addition to conventional electric resistive sheets so that, with but a slight expansion of the concept of resistivity, magneto-dielectric layers of physical materials may be modeled. In addition to the theoretical work, experimental results obtained by both the University of Michigan Radiation Laboratory and the Air Force Avionics Laboratory are compared with computed predictions.
