<P>PROBLEM TO BE SOLVED: To provide a radar device in which direction measurement accuracy is improved. <P>SOLUTION: The radar device includes: transmission antennas 10-1 to 10-5; a digital code generator 11; reception antennas 12-1 and 12-2; and a digital demodulator 13. The digital code generator 11 distributes signals modulated by pseudo noise codes A-C into five respectively, controls phase differences of five signals in phase shifters 114A-C respectively, and controls the five signals so that transmission directions become vehicle front right, vehicle front center, vehicle front left respectively in a horizontal surface. The signals outputted from each of the phase shifters 114A-C are superimposed on each of the signals modulated by the pseudo noise codes A-C and are transmitted. The digital demodulator 13 demodulates the signals respectively by using the pseudo noise codes A-C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
