News editors obtained the following quote from the background information supplied by the inventors:“Radar systems in general are designed to detect and measure parameters of a “target” through transmittingknown RF waveforms and then receiving and processing the signals reflected back from the target. Allreceived signal levels depend on the “radar cross section” (RCS) of the object, target or clutter. The RCSis a joint measure of reflectivity and effective surface area. It is effectively the composite of one or morescattering centres (Joseph B. Keller, “Geometrical theory of diffraction”, Journal of the Optical Societyof America, 52(2):116-130, February 1962). These are viewed as point sources on the reflecting surfaceand, given suitable receive antenna array geometries, the position of these can be estimated in 3D spaceby comparison of received phase and the estimate of range to the scattering centre (its transmission timedelay). This can yield a set of received intensities at co-ordinates for each radar measurement or “chirp”.
