Reduced palm intensity for track extraction

Reduced Palm intensity function is introduced for track extraction algorithms of filters based on finite point process models to compensate for the spatial, or pair, correlation among detected targets in the Bayes posterior process. Pair correlation function along with intensity and the reduced Palm intensity functions of the Bayes posterior process for the PHD filter are derived. An example is given for which reduced Palm intensity function is used to resolve targets not separated in the posterior intensity function.
