Microwave metamaterial aperture imaging radar (MMAIR) is capable of generating high resolution images without using mechanical scanning or antenna arrays. In MMAIR, metamaterial elements are specifically embeded into a parallel plate waveguide, whose resonance frequencies vary among a wide bandwidth. Different radiation fields are gained by wide-band waveforms, and the scene information are measured...
This paper introduces an analytic formulation for frequency dependence of radar cross-section (RCS) for arbitrarily shaped targets using geometric and physical optic approximation. Using this formulation, the frequency dependence of RCS can be computed in terms of a model measurement within a small frequency region. For the purpose of verification and comparison, the measurement of the model is carried...
