Patent attributes
A radar module using multiple polarizations according to an embodiment of the present invention comprises a transmission channel unit (Tx) including a 1-1st antenna and a 1-2nd antenna electromagnetic waves representing different for transmitting polarization characteristics; a reception channel unit (Rx) including N (where N is a natural number) reception channels including a 2-1st antenna and a 2-2nd antenna for receiving echo waves of the electromagnetic waves transmitted by the transmission channel unit to an object and reflected back from the object; and a control unit for selecting the driving mode of the transmission channel unit and the reception channel unit, wherein the 1-1st and 1-2nd antennas are configured so that the electromagnetic wave transmitted by the 1-1st antenna and the electromagnetic wave transmitted by the 1-2nd antenna represent orthogonal polarization characteristics.
