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-astronomy, radio-monitoring. The method of digital complex radio direction finding consists in selective spatial reception of radio-waves for a set of possible directions to its source with a linear phased antenna array through formation of an array of coherent time counts of input radio-signals for all receiving radio-channels and its digital complex spectral analysis. At that one obtains complex amplitudes of spectral components with frequencies that correspond to a set of possible previous directions to the source of radio emission. One determines extreme frequency to which maximal level of module of complex amplitude of spectral component corresponds. Then one separates the sub-array of spectral components that includes the component with extreme frequency. After that one divides it into real and imaginary components of respective complex analytical signal. Then one determines difference of its arguments that corresponds to spatial arrangement of two antenna elements of phased antenna array. After that by extreme frequency and with account of difference of arguments of complex analytical signal one determines the end direction to the source of radio emission. The invention makes it possible to increase operation speed of radio direction finding. |
