<p>A radar device comprising a transmission unit, a reception unit, an I-signal generation circuit, a Q-signal generation circuit, a peak detection circuit, a target detection circuit, and a distortion determination unit. The transmission unit transmits, at each prescribed cycle, a radar wave having the frequency thereof modulated along a time axis. The reception unit receives an incoming wave being the reflection wave of the radar wave transmitted by the transmission unit, and amplifies same using an amplifier. The I-signal generation circuit mixes the radar wave transmitted by the transmission unit, and the incoming wave received and amplified by a reception means, and generates an I signal being a real-number component of a beat signal. A Q-signal generation circuit shifts byπ/2 [rad] the phase of the radar wave transmitted by the transmission unit, mixes same and the incoming wave received and amplified by the reception unit, and generates a Q signal being an imaginary-number component of the beat signal.</p> |
