Abstract
In a frequency modulated continuous wave (FMCW) radar apparatus, a transmitting section transmits a transmission signal and a receiving section outputs a beat signal. During this output period, a frequency-intensity property of a bias power supply voltage supplied from a power supply bias circuit is obtained. On the basis of determining whether or not the obtained frequency-intensity property satisfies a predetermined oscillation condition, it is checked whether or not there occurs oscillation in the power supply bias circuit.
