The problem of statistical synthesis algorithm for radiometric image restoration in ultrawideband multiantenna radiometric systems of aperture synthesis is solved. The ambiguity function (AF) of such systems is defined and investigated. Modeling results of AF are given. A limit error of estimation is defined. Reasonability of transition to quasioptimal spatio-temporal radiometric signal processing in ultrawidebandband systems of aperture synthesis is justified.
