1. A method for discriminating targets using information derived from a sensor, comprising: receiving a plurality of observations corresponding to a target; retrieving probabilities of the observations associated with each of a plurality of states, wherein the states are based upon a statistical model associated with at least one target type; consolidating the probabilities of observations for each of the plurality of states using a weighted combination thereof; computing the probability of each state associated with the plurality of observations; selecting a state of the target based upon the computed probability of each state; and discriminating the target based upon the selected state.
