ABSTRAKT

The problem of statistical synthesis of correlated spatio-temporal signal processing algorithm (at the output of M-element antenna array) in an analytical form is solved by developed mathematical apparatus of the integral V-transformation that allows to remove the limitation on the synthesis of UWB spatio-temporal signal. More specifically, the algorithm of optimal signal processing at the output of M-element antenna array is derived in the analytical form. It allows to analyze the quality of estimations, obtained according to this algorithm, and to give physical interpretation of radiometric images, formed at the output of UWB systems. The structural scheme of UWB system with variable antenna quantity is developed in the simulated environment. The ambiguity functions of such systems, calculated for certain fixed antenna array geometries, were researched.
