Classification: CPC G | IPC G

Claim 6:
7. A method of near-far target identification in a radar, the method comprising:
setting one or more parameters associated with a transceiver for target detection at a first range;
conducting a first scan of an area associated a vehicle's path;
generating, based on the first scan, a first Range-Doppler (“RD”) map image corresponding to first received target reflections;
processing the first RD map image with a data pre-processing module coupled to the transceiver;
adjusting the one or more parameters associated with the transceiver for target detection at a second range different from the first range;
conducting a second scan;
generating, based on the second scan, a second RD map image corresponding to second received target reflections;
adaptively scaling the second RD map image with respect to the first RD map image;
stitching the first RD map image with the adaptively scaled second RD map image;
generating a composite RD map image that comprises the stitched first and adaptively scaled second RD map images;
detecting and identifying targets using the composite RD map image; and
focusing at least one radar scan on a specific area of a field of view upon identifying targets in the vehicle's path.
