Abstract: According to one embodiment, a radar device comprises a panel including clusters and a controller. The controller is configured to cause a first cluster of the clusters to transmit an electromagnetic wave to a target, cause the first cluster and at least one second cluster adjacent to the first cluster to receive a reflected wave from the target, and cause the first cluster and the at least one second cluster to output a reception signal. At least one cluster other than the first cluster and other than the at least one second cluster does not output the reception signal.
