Abstract : A synthetic aperture laser radar outputs a dual beam that overlaps at a distant object to form a moving fringe pattern. The object reflects back a return beam to the radar where a receiver makes a holographic image of the object on a photographic medium. The moving fringe pattern effectively increases the beam size that would be necessary if a stationary fringe pattern were used when the object moves across the pattern. (Author)
