METHOD FOR DETECTION AND LOCALIZATION OF COMPOSITE SIGNALS Russian patent published in 2006 - IPC G01S5/04 

FIELD: radio engineering, applicable in passive systems of radio monitoring for detection and localization in frequency, time, azimuth and angle of elevation of composite signals in the conditions of priory uncertainty in the form and range of existence.

SUBSTANCE: the result is attained due to optimization of formation of amplitude-phase distribution in the stages of detection and localization of signals, matching of frequency-time ranges tied up by the power spectrum of the detected signal and correlated amplitude-phase distributions, and comparison of the directions of income of signals formed by the algorithms of high resolution of various sub-classes. As a result, the loss of signal power is minimized at a detection and direction finding, as well as abnormal errors of direction finding are precluded and, as a result, the discernibleness of composite monofrequency and single-frequency signals with a low spectral power density on the background of noise and interference is essentially enhanced.

EFFECT: enhanced efficiency of detection and localization in frequency, time, azimuth and angle of elevation the three main classes of composite signals.
