ABSTRACT:
A microwave sensor includes a case 1 of an object apparatus in which a discharge may occur; the object apparatus 2; an antenna 3 which is attached to the object apparatus case 1 and receives a microwave signal generated by a discharge; a signal processing unit 4 which is connected to the antenna 3, amplifies and detects the microwave signal, mixes the microwave signal with an oscillating signal, converts the mixed signal to a video signal, and amplifies the video signal; and an output terminal 13 through which the video signal is output.
