1. A non-destructive detection system for detecting moisture inside of a building structure which is not visible from outside of the structure, said system comprising:

  • a transmitter for generating a series of ultra-wideband pulses;

    an ultra-wideband antenna unit for directing the pulses toward the building structure so that the pulses are reflected therefrom, and for receiving the reflected pulses;

    a receiver for processing the reflected pulses received by said antenna unit and for producing a corresponding output; and

    a controller for controlling said transmitter, said receiver and said antenna unit and for analyzing said output of said receiver for the presence of moisture inside of the building structure,said ultra-wideband antenna unit comprising means for providing a plurality of different antenna locations relative to the building structure and means for receiving reflected pulses from the different antenna locations relative to the building structure.
