Abstract

The measure of track correlation uncertainty was defined and was compared with the Shannon entropy measure and Hartley measure of information uncertainty.Then

the usage of track correlation uncertainty was expressed.Lastly

the requirements and a mathematic model for evaluating the track correlation uncertainty were proposed.Simulation results show that the track correlation uncertainty is measurable and can be correctly evaluated.The proposed evaluation method can quantitatively describe the effects of target separations

sensor measurement errors

correctness of track correlation

etc.to the track correlation uncertainty very well.Moreover

to the same input of correlation results

the proposed evaluating method can output almost the same evaluating results of track correlation uncertainty for the same correlated track pairs

no matter the sensors have systematic errors or not.
