✦ Synopsis

The signal enhancement algorithm of Cadzow is developed in the context of best approximation theory and Combettes' method of successive projections, which is a generalization of the method of projection on convex sets. The relevant mathematical methods are surveyed. Applications of the signal enhancement algorithm to direction-of-arrival array signal processing for narrow-band and wide-band sources, data interpolation, signal detection, and x-ray fluorescence spectrum processing are presented.

The mathematical method of projections onto convex sets was recently used for reconstructing images from incomplete data and a priori information. We have investigated the possibilities of extending these algorithms to enhancement of images distorted by some masking effect, by noise, or by an imperf
