Abstract
A system (100) for locating an object (114) includes a signal source (102) that generates a wideband signal (104) that includes a continuously variable frequency from a first frequency to a second frequency, a microwave metamaterial leaky wave antenna (106) that receives the wideband signal as an input and maps the wideband signal from the first frequency to the second frequency as electromagnetic radiation that increases as a function of an azimuthal direction (108,110,112), the microwave metamaterial leaky wave antenna (106) positionable to face toward an object that is within its field-of-view FOV, wherein the transceiver assembly is positioned to receive the electromagnetic radiation that is reflected from the object and convert the reflected electromagnetic radiation to a reflected electrical signal, and an analyzer (118) configured to identify a main beam frequency of the reflected electrical signal and determine an azimuthal angle (108,110,112) and distance to the object based on the main beam frequency.
