A new optical system concept for processing data from synthetic-aperture radars is described. The optical systems are multilens, anamorphic telescopes including spherical and cylindrical lenses. The new method has as its basis two well-known properties of lenses: (a) the longitudinal magnification of an imaging system is equal to the square of the lateral magnification; and (b) a telescope provides an image with magnification independent of the object position.
Kozma et al. (1972) studied this question.
