Abstract: This application provides a communication apparatus. The communication apparatus includes at least one transmit antenna unit, at least one receive antenna unit, and a signal processing unit. The signal processing unit is configured to: control the at least one transmit antenna unit and the at least one receive antenna unit to communicate with at least one first terminal on a first frequency band; control at least one target transmit antenna unit to send a radar signal on a second frequency band; and control at least one target receive antenna unit to receive a first echo signal on the second frequency band. The at least one transmit antenna unit includes the at least one target transmit antenna unit. The at least one receive antenna unit includes the at least one target receive antenna unit. The first frequency band and the second frequency band do not overlap.
