1. A method for imaging the interior elements of a structure, comprising the steps of:
- transmitting a narrow band signal through the structure,receiving the narrow band signal through a narrow band receiver over a range of signal paths extending from the transmitter and through the structure, andimaging the interior elements of the structure according to the effects of the interior elements on the electric and magnetic field components of the received signal over the range of signal paths.

Abstract
Spatial bandwidth imaging of the interior spaces and elements of a structure by transmission of low frequency, continuous-wave, narrow band signal or signals through the structure, measurement of the electric and magnetic components of the received signal received by narrow band Doppler or focused synthetic aperture methods over a range of signal paths extending from the transmitter and through the structure, and imaging of the effects of the interior space on the electric and magnetic components of the received signal.
