Abstract : An efficient computational technique for obtaining radar scattering cross sections of electrically small airplanes is achieved by using a wire-grid reaction method. In this method, the airplane shape is approximated by a grid of thin wires, thereby leading to a mathematical representation of the airplane in the form of matrix, whose elements are evaluated by established reaction techniques, and which when inverted, yield scattering data very efficiently. A variety of wire-grid approximations were postulated for square plates, circular cylinders and several airplane types. (Author)
