Abstract :
A new approach is considered for solving the problem of spatiotemporal signal processing in adaptive antenna arrays in conditions intensive correlated noise processes. The method of synthesis of robust algorithms is based on the game-theoretical principle of searching a minimum of the root-mean-square error that characterizes quality of received estimations of the existential spectra. The signal processing algorithms, constructed on this principle, relate to the class of minimax algorithms being invariant with respect to the prior uncertainty concerning noise distributions.
