From page 204...
... , optical signal processing, and holography were made mostly during the 12-year period from 1952 to 1964. In 1951 Carl Wiley of the Goodyear Corporation had suggested that data collected from a small moving antenna could be used to synthesize a receiving antenna with a much larger effective aperture, thus increasing its spatial resolution.
From page 205...
... Beginning in 1954, Emmett worked with Cutrona and Vivian to investigate optical processing using incoherent light. In 1955 he and Leonard Porcello spent several months studying optical correlators for SAR processing based on both incoherent and coherent light.
From page 206...
... The processing of SAR data by optical means remained the mainstay of the radar community until well into the 1980s, when advances enabled electronic computing. Gabor's concept of wavefront reconstruction had a number of serious deficiencies.
From page 207...
... . Emmett's work on SAR and holography had an enormous technical impact and was a major driving force in shaping the field of optical signal processing.
