Summary:A processor-implemented method in a vehicle for detecting objects from radar data includes: retrieving radar measurements taken at different periodic time increments; organizing the radar measurements into appropriate time windows; building a sequence cluster of radar measurements wherein the sequence cluster comprises a sliding window the latest time windows of radar measurements; removing noise from the sequence cluster of radar measurements by removing a cluster of radar measurements from the sequence cluster of radar measurements that is contradictory to a road topology map for an area in which the first object is estimated to be situated; and outputting the sequence cluster of radar measurements after removal of contradictory radar measurements as a new cluster of radar measurements.
