Radar oscillator capable of preventing leak of oscillation output

摘要

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, a radar oscillator is provided which employs a configuration in which an operation of an oscillating unit itself is alternately changed between an oscillating state and an oscillation stop state by a switch, rather than a configuration in which an output passage of an oscillation signal is switched to be opened and closed as in a conventional radar oscillator.
