RADAR APPARATUS

摘要

A radar apparatus includes 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 the target; detect, based on the target data set, a side wall along a current lane in which the host vehicle is traveling; determine whether or not there is a continuity between a previous target data set and a latest target data set, and in a case where there is no continuity between the previous target data set and the latest target data set, perform “extrapolation;” determine based on a frequency of the “extrapolation” 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.

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 the target; detect, based on the target data set, a wall along a current lane in which the host vehicle is traveling; determine whether or not there is a continuity between a previous target data set and a latest target data set, and in a case where there is no continuity between the previous target data set and the latest target data set, use a prediction target data set derived based on the previous 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, wherein in a case where (i) it is determined that there is the continuity between the latest target data set of the target and the previous target data set of a stationary object in the current lane and (ii) the target associated with the latest target data set is in a range of the wall, the signal processor uses the prediction data set.
