A REVIEW PAPER ON RADAR TRACKING
Eng. Hanadi Arbab Salih*
ABSTRACT
Tracking refers to a radar following the position of one or multiple targets in space. Before the tracking process, the radar has to detect targets and find their range, angular location, and sometimes velocity. The requirements on the accuracy of angle measurement for a tracking radar are more strict than those for a search radar. The principle of tracking radar is to use the error signal to adjust the antenna's pointing direction. The difference between the target direction and the reference direction, usually the axis of the antenna, is defined as the angular error. The tracking radar attempts to position the antenna with zero angular error (i.e., to locate the target along the reference direction). Tracking radars are classified by how the tracking errors are developed. The principal tracking schemes include lobe switching, conical scan and monopulse tracking.
