IMAGE FORMATION BY PASSIVE COLLECTION AND PROCESSING OF RADIO FREQUENCY SIGNALS ILLUMINATING AND SCATTERED BY CULTURAL FEATURES OF TERRESTRIAL REGION |
摘要 |
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 amplitute 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.
