Following a review of the synthetic aperture (hologram) radar concept, several new developments are described. The first is the acquiring of range information by holographic means alone (that is, without the use of pulses). This process acquires two-dimensional data from a one-dimensional record, comparable to the acquiring, in a two-dimensional hologram, of three-dimensional information. The second development utilizes broad band, incoherent signals for the illuminating and reference waves in a bistatic radar or sonar system, with narrow band filtering procedures for generating a plurality of one-dimensional zone plates. The third development permits the maximum range of synthetic aperture systems to be extended by many times. The paper concludes with a brief note discussing the parallel processing aspects of the synthetic aperture technique.
