Abstract: A method and apparatus are present for steering a radio frequency beam. The radio frequency beam is emitted from an array of antenna elements at a first angle into a lens at a location for the lens. The first angle of the radio frequency beam is changed to a second angle when the radio frequency beam exits the lens. The second angle changes when the location at which the radio frequency beam enters the lens changes. The second angle of the radio frequency beam is changed to a third angle when the radio frequency beam with the second angle passes through a negative index metamaterial lens located over the lens.

Abstract: A system, apparatus, and method are disclosed for a super-resolution imaging radar (SRIR). The SRIR employs a pulse signal generator that propagates bursts of radio frequency (RF) energy. Each burst contains a number of pulses. One pulse of each burst is an ancilla pulse, and the remaining pulses are propagated towards an object. An array bucket detector (ABD) collects pulses that are reflected from the object. Also, the ancilla pulses are propagated through a virtual lens. A virtual scanning detector detects the virtual ancilla electric field. A processor calculates a virtual ancilla electric field, which would be present at the scanning detector. Further, a coincidence circuit calculates a cross-time correlation function of the electric fields of the reflected pulses that are collected by the ABD and the virtual ancilla electric field. The coincidence circuit uses cross-time correlation function results to generate pixels of an image of the object.

Abstract: A system, method, and apparatus for a super resolution radar image extraction procedure are disclosed. The super-resolution imaging radar (SRIR) system involves a pulse signal generator, an array bucket detector, an ancilla beam detector, and a coincidence circuit. The pulse signal generator propagates N number of bursts of radio frequency (RF) energy, where each burst contains M number of dithered pulses. The pulses are propagated towards an object of interest and the ancilla beam detector. The array bucket detector collects pulses that are reflected from the object. The ancilla beam detector scans in a direction of the dithered pulses, and collects the dithered pulses. The coincidence circuit calculates a cross-time correlation function from the pulses that are collected by the array bucket detector and the ancilla beam detector. The coincidence circuit sums cross-time correlation function results to generate pixels of an image of the object.
