Millimeter-wave detector using terminally sensitive technique to accurately distinguish the metal target has been deeply studied.The system theory of Ka band radiometer is introduced from the point of view of engineering implementation.The sensitivity of the system and the echo signal of the target are analyzed,and the simulation figure is presented.The filed high-tower experiment is introduced,and the data analyzed in detail,experimental results show that sensitivity of the detector is below 1.5k,and it can accurately distinguish the center of metal target(10m~2) in the range of 15～150m.
