Statistical Correlation Distance for Platform-to-Platform Radar Integration.

摘要

The concept of using a statistical distance for associating target detections and tracks and for track maneuver detection has been used for sometime in tracking with search radars. The statistic normally used with collocated radars was derived using fundamental hypothesis-testing techniques. A parallel development using predicted positions as well as measured positions was performed, and a new statistical distance measure was obtained which would probably be of more use in integrating data from noncollocated sites. In general the form is quite complicated, but if the radar measurements are unbiased, if no bias exists between different radars, and if the predicted position is not corrupted by target maneuvers or previously missassigned detections, the statistical distance becomes easy to implement.
