A method for determination of radio wave arrival angle relates to electric measurement engineering and can be used in study of propagation of radio-waves at open lines. The novelty of the method for determination of the radio wave arrival angle is in primary generation of high-frequency oscillations with first frequency in the first channel of interferometer and oscillations with second frequency in the second channel of interferometer. High frequency oscillations are emitted through antennae of interferometer in direction of the third antenna where those are received, transformed in frequency and re-emitted in reverse direction. In the channels of interferometer those high-frequency oscillations are repetitively received and mixed with output oscillations. Phase difference of combination low-frequency components is measured and recorded. At the second step in the first channel of interferometer high-frequency oscillations with second frequency are generated, and in the second channel of interferometer oscillations with first frequency are generated. Once again phase difference of combination low-frequency components is measured with determination of arithmetic average value for the current measured phase difference and the one recorded before. By arithmetic mean phase difference obtained one determines radio wave arrival angle with high accuracy. |
