LOW ENERGY RADAR SYSTEM
First Claim
1. A low energy radar system comprising:
- a radar signal generator generating a radar signal;
a transmitter, coupled with said radar signal generator, transmitting said radar signal via a transmitting antenna;
a receiving array including a plurality of receiving antennas and a plurality of receivers, each antenna being coupled with a corresponding receiver, each of at least selected ones of said receivers receives a respective signal corresponding to reflections of the transmitted radar signal from a scene;
a processor including;
a radar signal processor, coupled with said receiving array, said radar signal processor determines a scene reflections map, said scene reflections map includes values representing reflection characteristics from each selected location in said scene;
a detector, coupled with said radar signal processor, detecting objects in the scene and the corresponding locations thereof according to said scene reflection map and a clutter map, said clutter map includes values representing clutter reflection characteristics from each selected location in said scene; and
a power controller, coupled with said radar signal generator, with said transmitter, with said receiving array and with said processor, after said transmitter transmitted said radar signal and said receiving array received said signal corresponding to reflections of said transmitted radar signal, said power controller shuts down at least one of said radar signal generator, said transmitter and said receiving array.
