Application of Displaced Beam Method on Antenna Radiation Pattern Measurement

The purpose of our work was to create software with implemented displaced beam method (DBM) that enables to transform of a Fresnel region antenna pattern to a far field pattern for linear and circular antenna apertures. Further goal was to carry out of the testing of this method. The developed software includes an effective technique for random errors elimination and a tool for systematic errors indication. The systematic errors are mostly caused by inaccurate antenna mounting on a turntable and rotating out of antenna phase centre in process of antenna radiation pattern measurement.
