ABSTRACT:
Provided is a radar apparatus that detects an object, and includes: an oscillating unit for generating carrier waves; first and second transmission units for spreading the carrier waves, respectively using a first pseudo-random code and a second pseudo-random code different from the first pseudo-random code; a first transmission antenna for transmitting the carrier waves spread by the first transmission unit; a second transmission antenna for transmitting the carrier waves spread by the second transmission unit and have a directional characteristic different from that of the carrier waves transmitted by the first transmission antenna; a reception antenna for receiving reflected waves that are the carrier waves that have been transmitted by the first and second transmission antennas and have been reflected from the object; and a reception unit for despreading the reflected waves, using the first pseudo-random code and despreading the reflected waves, using the second pseudo-random code.
