Evaluation of accuracy of correction factor at short at short distance measured gain of horn aerials in the microwave range

摘要

Comparison of two alternative methods of calculation of correction factors to measured at short distance gain of pyramidal horns - method of transmission of power from one aperture to the another and method of geometric theory of diffraction wasconducted. Using the received experimental data the evaluation of accuracy of correction factors depending on value of parameter n = Rλ/D{sup}2 was obtained.
