Sunyield SY-SPS is a single probe sliding rail spherical near-field testing scheme, mainly suitable for antenna testing in civil antenna manufacturers and military RCS testing.
Scattering near-field measurement is developed on the basis of radiation near-field measurement, and the near-field measurement of antennas has become a universal testing standard internationally, with higher accuracy than far-field testing. There are also three sampling methods for scattering near-field measurement, namely plane scattering near-field measurement, cylindrical scattering near-field measurement, and spherical scattering near-field measurement. Spherical near-field measurement has the advantages of high testing efficiency, large credible angle domain, and large amount of information
