The invention relates to radio electronics and can be used in radio-electronic means for different purposes, in particular in radio navigation, radio-location, radio-monitoring. In the method for digital complex direction finding one performs spatial reception of radio radiation for set of possible directions to its source with linear phase antenna grid through formation of massif of coherent time counts of initial radio-signals of at receiving radio-channels and its digital spectral analysis, one obtains complex amplitudes of spectral components with frequencies that correspond to set of possible previous directions to source of radio emission. One determines extreme frequency to which maximal level of module of complex amplitude of spectral component corresponds. After that from massif of coherent time counts of initial radio signals of all receiving radio channels with separation of sub-massif of its first counts, with implementation of complex digital analysis and with determination of complex amplitude of spectral component with extreme frequency. After that one determines difference of arguments of complex amplitudes of spectral components with extreme frequency determined for massif of coherent time counts of initial radio signals for all receiving radio-channels and sub-massif of first counts separated from it. After that by extreme frequency and with account of difference of arguments one determines the end direction to source of radio emission. The invention makes it possible to increase operation speed of direction finding. |
