Abstract

In the report it is shown, that the estimation of informative parameters of a signal against a noise back-ground does not depend on indeterminacy of its random initial phase. It is noted, that the obtained algorithm of measurement is reduced to the one based on a preliminary maximization of the LR by uninformative parameters, and it is more preferable than the algorithm based on averaging indicated parameters. The comparison of algorithms is carried out with reference to the task of measuring a receiving direction of a signal by the radar with an adaptive array against a noise hum of external spatially correlated interference.
