1. An object identification device combined with a millimeter-wave passive image system and global positioning system (GPS) for the blind, comprising:

  • a millimeter-wave passive image wireless circuit (31) that consists of a patch antenna array, a low-noise amplifier and a phase shifter required for the millimeter image system to transmit/receive the millimeter-wave for the detection of millimeter-wave image signals;

    a control unit that consists of an array antenna beam forming unit (321) for the beam forming of the millimeter-wave, a signal process unit (322) to analyze millimeter wave images, a GPS antenna (35) to receive position signals from a satellite and a GPS control unit (322) to control signals received from the GPS antenna;

    an operation unit (33) that consists of an object identification unit (331) and a position navigation unit (332) to constitute the information about the ambient situation by using signal-processed data; and

    an audio process unit (34) that consists of a voice process unit (341) for voice transformation using the millimeter image information and position information and a audio generation unit (342) to generate the transformed voice.
