Abstract
An apparatus includes a radome and an evanescent wave-coupled windowing system in the radome. In operation, the apparatus receives radiation reflected from an object that is incident upon a windowing system; emits evanescent waves from the windowing system whose amplitudes are proportional to the angle of incidence of the radiation; and non-coherent, Fresnel direction finds the object.
