Claim 0:
1. An adaptive radar for near-far target identification, comprising:
an antenna module configured to radiate a transmission signal with an analog beamforming antenna in a plurality of directions using one or more phase control elements in a first radar scan and to generate radar data capturing a surrounding environment of a vehicle's path;
a data pre-preprocessing module configured to receive the radar data and determine adjustments to at least one transceiver parameter in the antenna module for a second radar scan subsequent to the first radar scan based at least on range to regenerate radar data capturing the surrounding environment; and
a perception module configured to detect and identify targets in the surrounding environment from the radar data of the first radar scan and the regenerated radar data of the second radar scan, wherein the perception module is further configured to:
generate a first Range-Doppler (“RD”) map image corresponding to the first radar scan,
generate a second RD map image corresponding to the second radar scan,
adaptively scale the second RD map image with respect to the first RD map image,
stitch the first RD map image with the adaptively scaled second RD map image,
generate a composite image that comprises the stitched first and adaptively scaled second RD map images, and
focus at least one radar scan on a specific area of a field of view upon identifying targets in the vehicle's path.
