Hybrid Fence Alignment Analysis

This report describes the methods used to quantify the geometrical properties of the Naval Space Command Naval Space Surveillance Radar Fence. The Space Surveillance system was designed and began operations soon after the launch of the first earth satellites. Its mission is to track and catalog objects passing through the plane of the radar beams. The fence comprises three transmitting sites and six receiving sites spread from Georgia to California, making it one of the largest multistatic radar systems ever conceived. Because of the steady increase in the number of satellites launches and the associated orbiting debris from expendable launch vehicles, the number of objects in the catalog continues to grow. However, the catalog is not all inclusive and includes only a subset of all orbiting objects. At a time where the number of users of the catalog is increasing and the interest in a more complete and accurate description of the hazard is growing, improvements to the fence are being considered.Naval Surface Warfare Center Dahlgren Div VA is the author of 'Hybrid Fence Alignment Analysis' with ISBN 9781423553595 and ISBN 1423553594.
