1. A method comprising:
determining, by a processor of a radar system, that interference is present in a radar signal;
prior to generating radar data based on the radar signal, mitigating the interference from the radar signal by:
identifying a corrupted segment of the radar signal that corresponds to the interference;
determining a neighbor segment of the radar signal that is adjacent to the corrupted segment;
determining a match segment of the radar signal with similar signal characteristics as the neighbor segment;
determining a replacement segment of the radar signal that is adjacent to the match segment; and
adjusting, based on signal characteristics of the replacement segment, signal characteristics of the corrupted segment of the radar signal to generate a mitigated radar signal without the interference; and
generating, based on the mitigated radar signal, the radar data; and
outputting the radar data for at least detecting or tracking of objects in an environment of the radar system.
