Abstract:
1. A holographic imaging system comprising: an antenna having a transmission line coupled thereto, said transmission line coupled to the antenna at one end and coupled to a signal source at another end, said antenna defining an aperture through which a signal generated by the signal source is transmitted incident to an object located remotely from the aperture and through which a signal reflected from the object is received by the antenna aperture; a standing wave probe located at a distance from the antenna aperture, wherein the distance of the standing wave probe from the antenna aperture is a fraction of a wavelength of the signal generated by the signal source such that the standing wave probe is phase-referenced to the antenna aperture for sampling the reflected signal; a detector connected to the standing wave probe and configured to receive the sampled reflected signal, the detector providing an output signal that represents a real-valued signal proportional to an in-phase component of the reflected signal from the object and determining a reflection coefficient from the remote object measured at the aperture of the antenna; and a processor configured to execute an imaging algorithm for generating a multi-dimensional profile representative of the object based on the output signal from the detector.
