Abstract

The radar device is provided with a transmission array antenna, phase shifters, a reception array antenna, a transmission control unit and a signal processing unit. The transmission control unit transmits transmission waves in either a directivity control mode or a MIMO mode. The directivity control mode controls directivity of the transmission array antenna by controlling the phase shifters. The MIMO mode transmits transmission waves so as not to interfere with each other from the selected at least two transmission antenna elements.

Claims8

Dependent claims

A radar device, provided with a transmission array antenna provided with a plurality of transmission antenna elements, and configured to transmit transmission waves, and

phase shifters each provided to each of at least two of the transmission antenna elements, and configured to change the phase of the transmission waves transmitted from each of the transmission antenna elements provided with the phase shifter, and
a reception array antenna provided with a plurality of reception antenna elements, and configured to receive reflected waves generated by a target reflecting the transmitted transmission waves, and
a transmission control unit configured to transmit the transmission waves via the transmission array antenna by either a directivity control mode or a MIMO mode, wherein the directivity control mode is an operation mode of the radar device that controls directivity of the transmission array antenna by controlling the phase shifters, and the MIMO mode is an operation mode of the radar device that selects at least two of the transmission antenna elements from the plurality of transmission antenna elements, and transmits the transmission waves so as not to interfere with each other from the selected transmission antenna elements, and
a signal processing unit configured to estimate an orientation of the target from the reflected waves received by the reception array antenna.
