| Abstract(in English) | Identifying objects with radar is in great demand for avoiding road accidents. Recent research tried to identify moving objects on a road by inputting radar information to a machine learning classifier. In the conventional method, the features used in the machine learning are extracted from the observed radar information with a short time interval. Since the movement of the objects is different depending on the objects, time series information is effective for classification, which has not been exploited before. In this report, we propose a machine learning-based object identification using time series of radar information obtained from the time window that contains series of features. We extract features from a series of features by calculating the mean and variance of object information, i.e., velocity, signal power, and distance. Some experiments were carried out, and the classification performance was evaluated. From the classification results, it is shown that our method outperforms the conventional one of which features are extracted with a short time slice. It is also shown how much each feature contributes to the object identification in our method. |
