An imaging system uses 'RF daylight' created by an RF illumination source, such
as a television broadcast tower, to passively generate RF scattering coefficients
for multiple points within a prescribed three-dimensional volume being illuminated
by the RF transmitter. The scattering coefficients provide a complex interference
pattern having amplitude and phase components that contain all information necessary
to recreate a three-dimensional monochromatic image of the illuminated scene. Coherent
complex correlation provides scene information content that is only a function
of scene scattering and collector geometry. The scene information may be coupled
to an image utility subsystem, such as a virtual reality simulator, for generation
of a three-dimensional image of the illuminated scene.
