FIELD: radio engineering; monitoring changes in radio-electronic situation. ^ SUBSTANCE: proposed method includes reception of signals from multicomponent antenna assembly, their amplification, multiplication, filtration, submission of multiplication and filtration results in the form of correlation signal matrix, delay of these signals, element-by-element subtraction of signals of current and delayed signal matrix, and submission of subtraction results in the form of differential correlation matrix, additional measurement of differential signal correlation matrix polarity, and determination of signal belonging to radio-electronic means which has stopped or started radiation by its value, comparison of operating frequency value and direction of arrival of new radiation signal with all recorded values of operating frequencies and directions of signals arriving from radiation-stopping radio-electronic means which changed operating frequency in response to direction of arrival of this radio-electronic means signal. ^ EFFECT: ability of detecting signals from radio-electronic means which changed operating frequency. ^ 1 cl, 6 dwg |
