Currently much attention is paid to the tasks of remote sensing by radiometric systems and complexes. Developers of these systems improves their basic characteristics: fluctuation sensitivity, accuracy of parameters estimating.It is possible to improveRMSC characteristics using ultra-wideband predetection section and ultra-wideband spatio-temporal signals processing.Therefore, the theory of statistical analysis and synthesis ultra-wideband radiometric systemsacquires special importance. The mathematical foundations of this theory are represented in [1-3].
Taking into account the advantages of radiometric methods of extracting information it is interesting to use them for solving the problems of designing systems for water areas control.Such systems can be used for water transport control. Report contains the results of calculation of radiometric multi-antenna system that ensures the formation of water areas map and detected the ships. Usingultra-wideband predetection section it is possible toincrease desired accuracy of theproblemssolution of mapping and detection. It shows that the spatial resolution of the radiometric image significantly depends on the type of the antenna system geometry. The feasibility of using multiband receiver predetection sections of radiometric system is shown. The potential accuracy of images is investigated. The impact of the bandwidth of the receiver predetection section and antenna geometry on the potential accuracy of the estimates is investigated.  Volosyuk V. K., Kravchenko V.
