Abstract
In an embodiment, a method includes: receiving radar digital data; processing the radar digital data with a plurality of sine filters to generate a respective plurality of range-slow-time data, where each sine filter is associated with a respective range zone of a plurality of range zones; generating a first presence score based on a first range-slow-time data of the plurality of range-slow-time data, where the first range-slow-time data is associated with the first range zone; and when the first presence score is higher than a predetermined threshold, generating a plurality of synthetic antennas based on the first range-slow-time data, performing angle estimation based on the plurality of synthetic antennas to generate first probability values for a plurality of angle zones associated with the first range zone, and updating an occupancy grid map based on the first probability values.
