1. An improved ATR system for detecting, identifying and prioritizing targets from a plurality of detected targets, including:

  • a plurality of sensor means for detecting mutually exclusive sets of waves emanating from the environment including said targets;

    all of said sensors being passive and having response thresholds low enough to detect all possible targets including a very large number of false targets;

    a sub-ATR circuit means coupled to each of said sensors for locating, classifying, prioritizing and listing a separate preselected quota in each of a preselected number of classes of targets detected by said sensors, in accordance with prerecorded target signatures and other user constraints,a first of said sensors having a lower probability of detection for a given false alarm rate than a second of said sensors, but based on a different distribution pattern of false alarms among said targets;

    a final decision means coupled to all of said sensors for reassigning the classifications and priorities of targets detected by both of said sensors according to a preselected set of logical classification rules.
