Investigation of radar scattering from conducting and dielectric targets in the resonance region

Theoretical and experimental studies of radar scattering from conducting and dielectric targets in the resonance region are described. The formulation used is based on the equivalence principle which relates the total electric and magnetic fields on the surface of dielectric targets to that of the equivalent surface currents J and M. Measurements were conducted for two orthogonal linearly polarized transmit signals, and both the amplitude and phase of co- and cross-polarized return signals are measured over a wide frequency band. The monostatic scattering pattern of metallic cube of size L=2.46 cm is presented along with the backscattering pattern of a conducting rectangular strip of size L, thickness of 0.21L, and width of 0.074L, for a vertically polarized incident plane wave.<>
