提出了一种能有效探测隐蔽目标的新型主动毫米波准光学成像技术。其工作原理是基于对具有多次分解和编码的辐射的对象进行多参数主动照明，分别采集准光学部分图像，并随后对表现出增强的质量和信息含量的合成图像进行数字合成。该技术利用人造毫米波光源和开关元件的能力，在大范围的辐射物理参数范围内扫描和调制毫米波辐射。给出了实验和数值模拟结果。
A novel active millimeter-wave (MMW) quasi-optical imaging technique, which can be effectively used for detection of concealed objects, is presented. The operation principle is based on multi-parameter active illumination of the objects with multiply decomposed and encoded radiation, separate acquisition of quasi-optical partial images, and following digital synthesis of resultant images exhibiting enhanced quality and information content. The technique utilizes capabilities of artificial MMW sources and switching components to sweep and modulate MMW radiation within wide ranges of radiation physical parameters. Experimental and numerical simulation results are presented.
