PURPOSE: A manual millimeter wave imaging system is provided to achieve an image of an object by receiving spectrum intensity of a millimeter wave band radiated from the object in proportional to an absolute temperature of the object. CONSTITUTION: A manual millimeter wave imaging system includes a lens(10) for collecting thermal noise radiated from an object in proportional to an absolute temperature of the object. A chopper(20) is provided to shield a signal in order to create a reference signal. A horn antenna(30) receives a millimeter wave among thermal noise radiated from the object. A wave detector(50) is provided to convert a signal amplified by an amplifier(40) into direct current. An amp(60) outputs DC voltage by filtering a low frequency component from of the signal. An image processing computer(70) processes the DC signal so as to create an image.
