Abstract:
A system for detecting a target object through foliage and determining the target object's location, said system comprising:a transmitter for generating an electromagnetic signal for reflection from said target object, said signal having a frequency less than approximately eight hundred megahertz (800 MHz); a plurality of sensors for receiving said reflected signal from said target and generating signal information therefrom, said sensors being mutually dispersed at known locations; a means for coherently processing said signal information and said sensor locations to generate a set of possible target locations, said set including sidelobe ambiguities and the actual location of said target; at least one wireless link to send signal information from a said sensor to said processing means; and a beamforming means for suppressing said sidelobe ambiguities to resolve said actual location from said set of possible target locations.
