FIELD: the invention refers to measuring technique and may be used for passive detection and direction finding of communications systems, location and control, using complex signals.
SUBSTANCE: the technical result is achieved due to using of the reliability criterion of detection-direction finding and solution of the problem of the "reference signal" at compression of signal spectrum with low spectral power density of an unknown form. That approached quality of matched filtering at low signal-to-noise ratios to maximum attainable quality for the completely known reference signal. At that sensitivity of detection and direction finding of signals with extended spectrum increases in relation to the prototype in N times where N - a number of antennas of the receiving array.
EFFECT: increases effectiveness of detection-direction finding of the sources radiating broad class signals with extended spectrum of unknown form having energy and time secretiveness.
