| Abstract(in English) | We propose a novel active and coherent method for near field imaging in millimeter-wave band, namely the mod-ulation complex-amplitude observation method (MCOM). In the MCOM, the high-frequency circuit is so simple that it is low-cost and suitable for highly-parallel imaging. One of the possible applications is an anti-terrorism security system at ticket gates in railway stations where we observe walking people with their belongings. We report in particular that the phase image observed by the MCOM yields quite informative images. That is, the harmful glaring, which often occurs in active millimeter imaging, is mitigated effectively so that the shape of an objective is presented much better. We can choose arbitrary phase-distance sensitivity by adjusting the modulation frequency adaptively to the target of visualization. The system can be simpler than FMCW, and compatible with array antennas and parallel processing. |
