Portable device for the detection of concealed objects

A method of detecting concealed objects, the method comprising:

• scanning a target with microwave electromagnetic radiation;
• receiving a reflected signal from the target, the reflected signal corresponding to the microwave electromagnetic radiation;
• conditioning and converting analog data related to the received signal to a digital data format;
• processing the digital data;
• determining a condition corresponding to the digital data;
• generating a signal for an operator indicating the condition,
• wherein scanning the target comprises:
• generating the electromagnetic radiation;
• transmitting the electromagnetic radiation to the target with a vertical polarization transmitter;
• connecting a detector to a vertical receiving element;
• generating a signal based on radiation reflected from the target in response to the transmitted electromagnetic radiation;
• transmitting the signal to a signal conditioning and conversion module;
• generating additional electromagnetic radiation;
• transmitting the additional electromagnetic radiation to the target with a horizontal polarization transmitter;
• connecting the detector to the horizontal receiving element;
• generating an additional signal based on radiation reflected from the target in response to the transmitted additional electromagnetic radiation;
• transmitting the additional signal to the signal conditioning and conversion module.
