Called synthetic aperture radar (SAR), an ordinary-sized antenna fixed to the side of an aircraft is used with highly complex signal processing to give an image that would otherwise require a much larger, scanning antenna; thus, the name synthetic aperture. As each pulse is emitted, it is radiated over a lateral band onto the terrain.
It was during this time he invented synthetic aperture radar in 1951, patented as "Pulsed Doppler Radar Methods and Means," #3,196,436. That same year Wiley posited the idea of solar sails in a science fiction story published in Astounding Science Fiction magazine entitled Clipper Ships of Space (originally titled Are the Clipper Ships gone ...

To expedite the test, a synthetic-aperture radar designed for airborne use was adapted, by subcontractor Goodyear, to space operation and the long ranges involved, based on criteria developed by the research team at another participating organization whose relationship to Quill has not yet been declassified.
