Abstract

For weapon systems, most RCS measurements are captured in the near-field area in anechoic chamber, considering the security requirements for the research process and high spatial costs. So, It is necessary to convert the scattered wave measured in the near-field region to the RCS value in the far-field region. Therefore, this paper proposes a near-field to far-field transformation algorithm based on multi-level spherical wave expansion for application in near-field RCS measurement systems. It was verified that faster and more accurate RCS prediction is possible by supplementing this via a multi-level technique.
