Abstract :
The paper investigates spatial signal processing using antenna arrays. Main attention is paid to the optimization of spatial structure of antenna array to improve noise immunity and estimation accuracy of information parameters. Non-recurrent algorithm of spatial structure optimization with sequential samples is proposed. On the basis of statistical approximation the optimal spatial structure is estimated and the variance of the estimation error is defined.
