Patent ID: 8537049

Claim:
A multi-function radar apparatus having a high-frequency signal generating unit that supplies a frequency-modulated transmission signal, an antenna that emits the transmission signal to a target object and receives measurement information on the target object as a reception signal, a frequency converting unit that mixes the transmission signal and the reception signal to generate a beat signal, and a signal processing unit that performs measurement on the target object based on the beat signal, comprising: a transmission signal intermittent stop unit that intermittently stops emission of the transmission signal, wherein: the antenna receives a reflected wave from the target object as the measurement information while the transmission signal is emitted, and receives a radiated wave from the target object as the measurement information while the transmission signal is not emitted; and the signal processing unit measures a distance to the target object based on the beat signal while the transmission signal is emitted, and measures a temperature of the target object based on the beat signal while the transmission signal is not emitted.
