Abstract: A detection system includes an obtainer, a generator, a classifier, a centroid calculator, associator, and combiner. The obtainer obtains a reception signal from a radio wave sensor. The generator generates a scattered point including positional information of a target, based on the reception signal. The classifier classifies a scattered point group into one or more clusters. The scattered point group is a set of scattered points generated by the generator during a predetermined length of time. The centroid calculator calculates a centroid for each of the one or more clusters classified by the classifier. The associator associates any of the one or more clusters classified by the classifier with the target. The combiner combines, as the scattered point, the centroid calculated by the centroid calculator during a preceding or earlier period with the scattered point group.
