Necessity of an estimation of radiation pattern of each radiator is shown at diagnostics low-element antenna arrays. Analytical expressions for reception of estimations of equivalent pattern of radiators in phased array are resulted by a method of discrete transformation Walsh. Results of practical check testify that mutual couplings of elements of low-element phased array essentially influence of radiation pattern of radiators in antenna array. Results of experiment are well be matched with the given received other authors.
