To satisfy a requested performance under various conditions.SOLUTION: A radar device includes: a transmitter; a receiver; a mixer; and a processor. The transmitter transmits transmission waves in which a frequency changes continuously. The receiver receives reflection waves of the transmission waves by an object. The mixer mixes the transmission waves with the reflection waves. The processor switches a mode for mixing the transmission waves with the reflection waves in a phase in the one mixer and a mode for mixing the transmission waves and the reflection waves in a phase and out of a phase in the two mixers.SELECTED DRAWING: Figure 1
【課題】種々の条件において要求性能を満たす。【解決手段】レーダー装置は、送信機と、受信機と、混合器と、プロセッサと、を備える。送信機は、連続的に周波数が変化する送信波を送信する。受信機は、前記送信波の物体における反射波を受信する。混合器は、前記送信波と、前記反射波と、を混合する。プロセッサは、1つの前記混合器において、前記送信波と前記反射波とを同位相で混合するモードと、2つの前記混合器において、前記送信波と前記反射波とを同位相及び異なる位相で混合するモードと、を切り替える。【選択図】図1
