Error Compensation or Radome Measurements

Author:Scott T. McBride

Geometries for measuring radome characteristics can usually be split into two categories. The first category always has the antenna inside the radome pointing along the range axis. The second category has the antenna maintaining a fixed relationship with respect to the radome during each scan of data.

A facility can generally be designed to minimize measurement errors in one of the two geometries, but not both. Many facilities that permit collection of data in both geometries would benefit from the ability to dynamically capture data that lead to measurement errors, then compute and remove the associated errors.

This paper discusses some of the primary error contributors in a dual-geometry radome measurement system, and suggests some mechanisms for capturing and potentially removing those errors.
