Abstract
The increasing interest in security and surveillance issues has motivated the research and development of this type of system through the design of new detectors [2] and receiver modules [3], [4]. In the literature, we can find passive MMW (PMMW) systems [5]?[7], active MMW systems [8], [9], active terahertz (THz) systems [10], [11] and radar systems at THz frequencies [12]?[14] actively being studied. Most PMMW systems perform a mechanical scan of the scene and use the natural radiation from the objects in the scene to obtain the MMW image. (The MMW imaging acquisition process is detailed in ?Operating Principles of MMW Imaging.?) These systems normally work below 100 GHz (mainly at 77 and 94 GHz), due to limitations of the highfrequency RF components in terms of power, noise figure, frequency, stability, and cost. The major drawback of passive systems is that, in an indoor scenario with no celestial cold radiation, objects in the scene will only appear in the image if they are in front of an object that emits hotter radiation.
