1. A radar apparatus that acquires a target data set of a target near a host vehicle, the radar apparatus comprising:

  • a signal processor configured to;

    derive the target data set of the target, in a predetermined time cycle, based on a reception signal acquired by receiving a reflection wave from an environment including the target;

    detect presence of a wall along a current lane in which the host vehicle is traveling;

    determine whether or not there is a temporal continuity between a previous target data set and a latest target data set, in a case where there is the latest target data set that has a continuity with the previous target data set, use the latest target data set, and in a case where there is no latest target data set that has the temporal continuity with the previous target data set, use a prediction target data set derived based on the previous target data set as the latest target data set; and

    determine, based on a frequency of use of the prediction target data set, whether or not the target associated with the target data set is an upper object overhead of the vehicle and with which the vehicle cannot collide, whereineven if there is the latest target data set that has the continuity with the previous target data set, in a case where (i) the target is associated with the previous target data set is a stationary object in the current lane and (ii) the target associated with the latest target data set is within a predetermined threshold distance of the wall, the signal processor uses the prediction target data set instead of the latest target data set.
