Abstract:
    A radar oscillator includes an oscillation unit and a first and a second switch circuit so as to intermittently output an oscillation signal according to a pulse signal indicating the radar wave transmission timing without causing a leak. The first switch circuit turns off power supply to an amplifier for a non-input period of the pulse signal so as to set the oscillator to an oscillation stop state and turns on power supply to the amplifier for the input period of the pulse signal to set the oscillator to an oscillation state. The second switch circuit turns on power supply to an LC resonator to supply a predetermined current to the LC resonator for a predetermined non-input period of the pulse signal up to the moment immediately before the input of the pulse signal and turns off power supply to the LC resonator at the timing when the pulse signal is inputted so as to stop supply of the predetermined current to the LC resonator, thereby promoting the start of the oscillation operation of the oscillator.
