Abstract
A radar device includes a signal processing unit and a target information output unit. The target information output unit outputs only pair data having addition reliability equal to or larger than a threshold to the outside of the radar device as target information. The signal processing unit determines whether a first target and a second target belong to the same object. The first target is pair data derived later than the second target. If it is determined that the first target and the second target belong to the same object, the signal processing unit transfers reliability of the second target to the first target.
Claims20
A radar device for deriving information related to a target based on a reception signal that is acquired by receiving a reflected wave obtained when a transmission wave transmitted to a periphery of an own vehicle is reflected by an object present in the periphery, the radar device comprising:
- a determination unit that determines whether a plurality of targets belongs to a same object;
- and
- a transfer unit that transfers, when it is determined that the plurality of targets belongs to the same object, information related to a classification of a second target as information related to a classification of a first target among the plurality of targets when the first target is a target present at a closer position than the second target and the second target is a target derived earlier than the first target.
An information transfer method for a radar device for deriving information related to a target based on a reception signal that is acquired by receiving a reflected wave obtained when a transmission wave transmitted to a periphery of an own vehicle is reflected by an object present in the periphery, the information transfer method comprising:
- determining whether a plurality of targets belongs to a same object;
- and
- transferring, when it is determined that the plurality of targets belongs to the same object, information related to a classification of a second target as information related to a classification of a first target among the plurality of targets when the first target is a target present at a closer position than the second target and the second target is a target derived earlier than the first target.
