Radar apparatus, antenna appartus and data acquisition method

The present invention relates to a radar device, the antenna device and data acquisition method. The invention, in one embodiment, the plurality of transmission antennas and plurality of reception antennas the antenna unit, a transmission or a plurality of transmitting antennas a transmission signal through the transmission antenna switched by the open-circuit switching of the plurality of transmission antennas, including the transmitting a transmission signal via the allocated multi-transmission channel, and to receive the reflected signal is the received signal reflected by the transmission signal transmitted through the receiving antenna switched to the open-circuit switching of the plurality of receiving antennas a target or a plurality of receive antennas through a multi-channel receiver is assigned to provide a radar device including a transceiver for receiving a received signal. The present invention relates to a radar device, the antenna device and data acquisition method. More specifically, while maintaining the angular resolution of the resolution, there is an effect that it is possible to reduce the size of the radar device.
