Abstract :
Analytic relations allowing to estimate the possible meanings of the signal/noise ratio depending on the parameters of antenna system and signals (number and step of radiator displacement, receiving signals covariance degree) are suggested. The relations are obtained for the contemporary methods of adaptive spatial filtration and estimation of spatial spectrum using the inverse covariance matrix. The results of mathematical modeling of signal processing based on the algorithm are given. Global character of radio-electronic systems use causes sufficient complication of electromagnetic situation. Efficient use of separated frequencies and ensuring desired accuracy of radio-electronic systems functioning under these circumstances is possible only when guaranteeing the set level of indirect radiation. In these terms the answer to the questions of ensuring the electromagnetic compatibility and electromagnetic ecology is connected to the increase of spatial selectivity when radiating and receiving radio signals. The approach realization basis is forming of required parameters of antenna pattern.
