Abstract :
A new approach is considered for solving the problem of spatiotemporal signal processing in adaptive antenna arrays working in conditions of 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 the quality of received estimations of existential spectra. The signal processing algorithms, constructed on this principle, relate to the class of maximal algorithms being invariant with respect to the prior uncertainty concerning noise distribution.
