Beschreibung
Zusammenfassung:	Provided is a radar device that can acquire three-dimensional information while mitigating an increase in the complexity and size of the device structure. A radar device 100 comprises: an antenna 110 having frequency characteristics in which the emission angle of the elevation angle direction changes according to the supplied frequency; a transmission signal formation unit (control/processing unit 101, oscillator 102, amplifier 103) that supplies a chirp signal to the antenna 110; and a reception processing unit (control/processing unit 101) that acquires a detection point for each frequency band using a reception signal for a transmission signal of each frequency band included in the chirp signal, and that acquires information regarding the height direction on the basis of the presence or absence of the detection points across a plurality of frequency bands.
