One-Dimensional-Array Millimeter-Wave Imaging of Moving Targets for Security Purpose Based on Complex-Valued Self-Organizing Map (CSOM)

Shogo Onojima, Akira Hirose

Abstract: We propose a millimeter-wave imaging system for moving targets consisting of one-dimensional array antenna, parallel front-end and complex-valued self-organizing map (CSOM) to deal with complex texture. Experiments demonstrate that the CSOM visualizes successfully a liquid-filled small plastic bottle even for measurement data in which we can see almost random phase and amplitude.
