Abstract:

In air defense and air traffic control systems, data from the system radars are stereographically projected onto a common coordinate plane for presentation to system operators. The stereographic projection of radar data involves two steps stereographic projection using slant range, azimuth and height information to obtain polar coordinates in a plane of projection centered at the radar site, and transformation of the radar coordinates into cartesian coordinates on a common coordinate plane. This report describes analysis that was performed on the stereographic projection process. The results indicate that the SAGEBUIC equations for stereographic ground range produce unacceptably large registration errors when extended to a large region. The results further indicate that the error can be corrected by a simple modification of the SAGEBUIC equations.
