Allowance for a priori indeterminacy in the statistical optimization of phase direction-finders

A statistical optimization procedure is proposed to overcome the a priori indeterminacy associated with the fact that the inverse correlation matrix of phase error is unknown for a multibasis phase direction-finder operating on the basis of fluctuating signals on tropospheric propagation paths. It is shown that it is not suitable, under the conditions of the adopted model, to apply the adaptive approach to the design of multibasis phase direction-finders. The minimax principle makes it possible to determine the parameters of a 'stiff' system for the processing of phase differences on the basis of given limits of signal parameter variations, depending on the operating conditions of the direction finder.
