Radar oscillator capable of preventing leak of oscillation output

摘要

The present invention, in order to enable intermittent output of an oscillation signal without essentially producing a leak in response to a pulse signal indicating a transmission timing of a radar wave, employs a configuration in which an operation of an oscillating unit ( 21 ) itself of a radar oscillator is alternately changed between an oscillating state and an oscillation stop state by a switch ( 30 ), not a configuration in which an output passage of an oscillation signal is switched to be opened and closed as in a conventional radar oscillator.
