The method of the spacecraft antenna system directivity pattern approximation by the terrestrial adjusting system signals

Abstract: The authors proposed a method of the directivity pattern approximation for the antenna system used in the multichannel terrestrial radiation sources finding. Approximation algorithm is simulated. Requirements to the input data selection and the approximating function parameters are defined. Accuracy of the antenna pattern approximation for different pattern forms and for different signal-to-noise ratios is estimated.

Keywords: antenna pattern, upper frequency limit, nyquist’s function, node point, absolute approxima- tion error, relative approximation error
