Abstract: Suboptimal algorithms were developed for the digital processing of narrow-band and wide-band signals in radiometric aperture synthesis systems, functional diagrams of the corresponding processing devices are given. These devices are sufficiently simple, and their quality characteristics are close to those which can be theoretically attained. An algorithm for noncoherent accumulation of images is discussed, it allows the sensitivity of radiometric systems to be improved substantially without any additional complications in the equipment.
