Abstract
Constructing a real‐time high‐resolution imaging operator has been one of the most important objectives in image reconstruction. It is especially desirable to holographic, tomographic, and synthetic aperture radar systems with limited detection apertures. This paper introduces a method of constructing such an operator by using the step size generated from the steepest descent algorithm to improve the resolution of backward‐projected images. With this operator we can overcome resolution limitations due to small‐sized apertures and it is not necessary to go through tedious computations as in the case with iterative algorithms.
