Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an azimuth detection device able to achieve a wide angle of an azimuth detection range with a simple configuration.SOLUTION: Digital data Dto Dare obtained (S110 to S180) for M×N channels CHto CH, which are combinations of an M number of transmission side antenna elements composing a transmission array antenna and an N number of reception side antenna elements composing a reception array antenna. The reception side antennal elements ARcarries out beam streaming (FFT) for the M number of channels CHto CHthat are common. From the result of the calculation, beam streaming (FFT) is carried out for each of the N number of the results of the calculations for the same frequency bin. Based on the distribution of reception intensity obtained from the result of this calculation, the azimuth of a target is extracted (S190 to S210).
