A cross-traffic detection system (10) suitable for use on an automated vehicle includes an object-detector (14) and a controller (24). The object-detector (14) is used to determine locations (16) of a moving-object (18) relative to a host-vehicle (12). Each of the locations (16) is indicated by a lateral-distance (20) and a longitudinal-distance (22) of the moving-object (18) from the host-vehicle (12). The controller (24) is in communication with the object-detector (14). The controller (24) is configured to accumulate a plurality of first-longitudinal-distances (26) of a first-vehicle (30) at a plurality of predetermined-lateral-distances (28), and determine a path-history (40) of the first-vehicle (30) based on linear-interpolation between successive instances of the plurality of first-longitudinal-distances (26) at corresponding instances of the plurality of predetermined-lateral-distances (28). The controller (24) is also configured to determine that a second-vehicle (44) is following the path-history (40) of the first-vehicle (30) when the second-vehicle (44) passes within an offset-distance (46) to the path-history (40) that is less than an offset-threshold (48), and estimate a crossing-distance (54) from the host-vehicle (12) based on the path-history (40) and the offset-distance (46).
