FIELD: physics, radio. ^ SUBSTANCE: invention relates to radio engineering and particularly to radio direction finding. Faster determination of bearings is achieved by using characteristic properties of linear components of an antenna system. The method for high-speed determination, with known azimuthal bearing , values of the elevation bearing and the amplitude and the signal from a radio source involves selecting two components of the antenna system, restoring the complex amplitude vector of signals y1 and y2 from outputs of the selected components. Further, y1 and y2 are transmitted to a divider (y2/y1) with calculation of the cosine of the elevation bearing at the output of the divide using the formula: where is the wavelength of the signal from the radio source, d is the distance between the selected components of the antenna system. Further, the elevation angle is calculated through a trigonometric arccosine function, and the amplitude and the signal from the radio source are then determined from the formula of the restored complex amplitude vector of the signals. Additionally, to increase accuracy of results, statistical dispersion of the obtained values of the amplitude and the signal and the elevation bearing is determined from a general formula: where f(x) -cos or u; x1, i=1Ç6(k=6); x1=; x2=d; x3=cos; x5ëå is the initial phase of the signal y1 or y2; x6ëy1 or y2; using analytical expressions of partial derivatives and predetermined dispersion values D(x1) of variables x1. ^ EFFECT: significant simplification, minimisation of the number of components and apparatus for portable direction finders when locating signal (separate) signals, significant increase in speed and accuracy of determining elevation bearings when receiving radio signals from one radio source using linear and nonlinear (including annular) antenna systems, consisting of weakly directional components (dipoles), and having two synchronised detection channels and a known azimuthal bearing of radio radiation. ^ 2 cl |
