Collecting two-way radar data across the entire pitch and yaw axes of an air vehicle is a difficult challenge.  Fortunately, it is rarely necessary to need the full sphere of RCS data as a full ring of yaw over a limited span of pitch will usually suffice.  However, when it is necessary to collect the full span of the pitch axis as well, there is a solution to accommodate this need.  It is based on a turntable used in a non-traditional way. Data collection will capture one full hemisphere in a single data collection, and then the inverted data collection run is added to complete the full spherical data set.
