NSI-MI Technologies Advanced Antenna Pattern Correction software enhances the accuracy of antenna pattern measurements. This is very useful for reducing the error in characterizing low sidelobe antennas.
The analysis package operates by mathematically analyzing several measurements of an antenna to characterize the interference signals across the pattern of the antenna. Once the interference spectrum is determined, it can be removed from the antenna measurement. Typical results achieve a reduction of 10 to 15 dB in the interference signals of the antenna. Actual results vary according to the antenna under test, the chamber design and metrology practices.
A manual or automated slide axis is required to provide a means of differentiating the data to determine interference. The slide axis can be transverse or longitudinal to the test range.
