Radar tracker
From Wikipedia, the free encyclopedia
A radar tracker is a component of a radar system that aggregates individual radar observations into tracks. It is particularly useful when the radar system is reporting data from several different targets. A tracker operates by comparing the incoming data from the radar sensor with earlier data and determining which new observations are consistent with existing tracks. A typical tracker employs a Kalman filter or a similar device to make the comparison. Depending on the particular data produced by the sensor, the tracker may use a sequence of the target's reported locations to deduce the target's course and speed, or it may use the reported course and speed to aid in tracking.
