Status of Sidelooking Radar Imagery for Earth Resources Studies
High-resolution sidelooking radar imagery was obtained for the Earth Resources Survey Program of the National Aeronautics and Space Administration (NASA). The several images that have appeared in the scientific and popular press have evoked much interest. The published pictures represent a very small fraction of the several hundred thousand square miles imaged in 112 flight hours. There is at least token imagery in 45 States. Much of this coverage was obtained in point-to-point flying between test sites. A new source of radar imagery, a sidelooking imager installed in a NASA aircraft, is scheduled to become operational.
