FIELD: radio engineering, communication.
SUBSTANCE: method involves further multiplication and low-pass filtering of the output voltage of each antenna element with reference signal voltages corresponding to all antenna elements and presenting the multiplication and filtration results in form of a cross-correlation matrix of signals; performing corresponding multiplication, summation and subtraction operations with signals of corresponding elements of the cross-correlation matrix of signals to obtain the determinant of the cross-correlation matrix of signals; finding the maximum value of the determinant of the cross-correlation matrix of signals and, for the maximum value of the determinant of the cross-correlation matrix of signals, based on reference signal parameters, determining the frequency value and direction of arrival of the signal of continuously emitting radio-electronic equipment.
EFFECT: detection of signals of continuously operating radio-electronic equipment.
