Abstract
The efficiency of adaptive spatial signal processing in arrays providing the maximum signal/noise ratio is studied for the case when the number of sample vectors is less than the number of elements of the adaptive array (AA) and there is no inverse correlation matrix of a jammer in the AA receiving channels. Three methods for defining the stable solution for the weight vector in the AA, which are based on supplementing a posteriori information on the jammer with a priori data on them, are studied. These methods are almost equally highly efficient, but the latter method requires considerably less calculation. Results of mathematical simulation of the efficiency of the suggested methods are given.
