Abstract:
A breakup event may produce large number of detectable targets for radar while tracking a space object. In a short time after the event, the breakups will stay close and keep unresolvable in radar angles which make great difficulties for target correlation and tracking, and false or unstable tracks frequently occurs during this time. In order to deal with the problem, a correction algorithm based on distance shift is proposed, simulation shows that it greatly improves the tracking results for space dense targets.
