摘要：
Passive millimeter-wave imaging is attractive due to the ability to obtain images in low-visibility conditions. In this paper, a passive millimeter-wave imaging method using photonic processing is presented. The principle of the millimeter-wave photonic signal processing method is described. The relationship between the signal conversion gain and the component parameters is discussed. The noise characteristic of this detection method is analyzed. A millimeter-wave radiometer using photonic processing is presented in this paper. A passive millimeter-wave scanning imaging system using this processing method was implemented. The imaging experiment results show that this imaging method is effective.
