For radiometric imaging (RMI) with high spatial resolution are used aperture synthesis systems. The basis cell of such system is the two-antennas radio interferometer. Optimal and quazioptimal algorithms for passive radar imaging by it radio interferometer with ultrawideband spatio-temporal signal processing are known. At the same time questions the limit estimation error of the RMI and the potential fluctuation sensitivity of such systems are not investigated. In the article for the first time the analytical expressions for the limit estimation error of RMI and the potential fluctuation sensitivity of two-antenna UWB aperture synthesis system that provides a high spatial resolution of the angular coordinates are obtained and investigated.
