This invention relates to the field of radar dynamic clutter maps, and specifically to a method and system for processing flight tracks based on radar point traces to generate dynamic clutter maps. This invention processes the amplitude and velocity information of nine adjacent cells at the range and azimuth of a target cell to obtain a preliminary judgment of the target cell's clutter situation. The flight track information is then compared with the similarity features of the corresponding clutter map cells in a pre-stored flight track clutter map. If it is a clutter track, it is removed from the radar display; if it is a suspected target, it is uploaded to the radar display interface for display. This invention employs a flight track clutter suppression method based on clutter maps, which can effectively suppress fixed clutter and residual slow-moving clutter, thereby eliminating false alarms caused by the movement of low-speed targets at range and azimuth.
