FIELD: measuring equipment, possible use in acoustics and radio-engineering for reproducing images and determining, with increased resolution, azimuth and local angle directions towards sources of waves of various nature: resilient waves in different substances, in particular, sound waves, waves on surface of liquid and electromagnetic waves.
SUBSTANCE: method includes using nonlinear pseudo-request algorithm, providing optimization of operations of nonlinear processing of signals at each iteration of radio image restoration process (complex angular spectrum) without using normalization parameter.
EFFECT: increased direction-finding efficiency of closely located sources of radiation of coherent signals of waves of various natures.
