を特徴とするミリ波レーダ装置。 an antenna that receives noise power in the millimeter wave band radiated from an object; a local oscillator; a mixer that converts the noise frequency received by the antenna into an intermediate frequency using the output signal of the local oscillator; The connected 1/4 wavelength transmission line, the single-throw single-pole switch connected between the antenna and the transmission line, the amplifier that amplifies the output of the mixer, and the single-throw single-pole switch are electrically connected. When the noise power of the object received by the antenna is introduced through the single-throw single-pole switch, the transmission line, the mixer, and the amplifier, and when the single-throw single-pole switch is open, the noise power of the object received by the antenna is introduced through the transmission line and the mixer. A detection unit that calculates the equivalent noise temperature of the object based on the temperature TO of the internal noise power by introducing internal noise power at a temperature TO generated at the temperature TO and calculating a ratio between the noise power of the object and the internal noise power. A millimeter wave radar device comprising:
