DYNAMIC ALLOCATION OF RADAR BEAMS IN AUTOMOTIVE ENVIRONMENTS WITH PHASED ARRAY RADAR

摘要

A radar apparatus that focuses a subset of transmit beams within a field of view (FOV) is provided. The radar apparatus has a phased array transmitter that is operable to generate a transmit beam within the FOV, and a phased array receiver that is operable to receive a receive beam reflected from within the FOV. The apparatus also has a radar controller with an electronic circuit and electronic memory, the electronic memory having a plurality of pre-calculated beam density curves. The radar controller is operable to execute each of the plurality of pre-calculated beam density curves and steer at least one transmit beam generated from a particular executed beam density curve towards a sub-area of the FOV.
