Abstract: Methods and systems for discriminating targets using information derived from a sensor are presented. In one embodiment, a method features receiving a plurality of observations corresponding to a target; retrieving probabilities of the observations associated with each of a plurality of states, where the states are based 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; 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.

Abstract: Methods and apparatuses for target radial extent determination using deconvolution are presented. One embodiment features a method for determining a radial extent of an target using an active sensor performing noise reduction on a received signal, deconvolving the noise reduced received signal by a transmit signal to produce a target profile, where both the noise reduced received signal and the transmit signal are over-sampled, and determining the target radial extent using the target profile. Another embodiment further features transforming the digitized transmit signal, transforming the digitized receive signal, thresholding the transformed digitized receive signal, dividing the noise reduced, transformed digitized receive signal by the transformed digitized transmit signal, and inverse transforming the divided signal.
