A high precision target classification between different traffic participants that are of a complex composition, is the prerequisite for the follow-up tasks of autonomous driving such as planning decision. Millimeter-wave radar has drawn wide attention because of its robust capacity to observe all-weather and all day, but the traditional methods that are based on signal features has limitations, so they are not suitable for a direct application on autonomous driving. In this paper we have designed a traffic-participants-classification algorithm directed at the point cloud data that are attained with millimeter-wave radar. Besides, we carried out an experiment using high resolution 4-D millimeter-wave radar to collect our datasets, and then test the proposed algorithm, which contains manually extracted 14 features designed by us, with our data. Finally, the classification results are visualized and some comparisons are made. The proposed method can reach an average accuracy above 95% in 10-fold cross validation cross the 3 collected datasets, and the general performance better than the method in the reference.
