FIELD: radio engineering. SUBSTANCE: method of signal processing includes following operations: formation of radiation pattern, sequential manipulation by each of formed radiation patterns W1, W2, W3, W4 with positioning of radiation pattern towards "cold sky" W5, manipulation by pairs of formed radiation patterns W1, W2, W3, W4 in planes of direction finding, reception of signal, frequency selection of signal, demodulation of signal by manipulation, extraction of signals W1-W5, W2-W5, W3-W4, W4-W4, computation of summary signals in planes of direction finding (W1-W5)+(W3-W5), (W2-W5)+(W4-W5), demodulation of signals by switching-over frequency in each plane of direction finding, extraction of error signals by azimuth Δβ = W2-W4 and elevation angle Δε = W1-W3; by normalization of error signals Δβ and Δε to proper summary signals 
, generation of proper errors Δβ′ and Δε′ in planes of direction finding. EFFECT: increased precision of direction finding in wide dynamic range of variation of levels of signals. 3 dwg
