The invention provides a statistical evaluation method and system for the detection range of a sea radar and belongs to the field of evaluation of the detection range of the radar. The method comprises steps of representing historical track data in a polar coordinate system with the radar as an original point; selecting a map corresponding to the radar, and superposing the historical track data subjected to polar coordinate system conversion and the radar on the map; taking the radar as a circle center, finding out historical track data points closest to and farthest from the radar on each azimuth angle in the map, and connecting the historical track data points into a broken line to obtain an initial morphology range detected by the radar; adopting a DBSCAN algorithm to eliminate outlier points in the initial morphology range of radar detection, and obtaining an optimized morphology range of radar detection; a plurality of distance scales being arranged in the optimized morphology range of radar detection, a
