1. A method of evaluating the tracking of a maneuvering target using at least two passive sensors relatively spaced comprising the steps of:

  • storing target data received from each passive sensor;

    predicting a target position from stored target data;

    deriving a track quality statistic from stored target data;

    determining an inclination angle statistic from stored target data; and

    evaluating whether a target track is maneuvering based on said track quality statistic and said inclination angle statistic.
