| Abstract | Abstract : The phase-only Consensus Correlator improves the probability of detection of targets obscured by other objects such as a stand of trees. The technique involves masking out most of the input scene and using a standard correlator to search for small pieces of the expected target shape. The areas of the input scene that are found to contain pieces of the target are combined in a final correlation. The Consensus Correlator reduces the transfer of noise that is interspersed with pieces of the target in the input scene to the vicinity of the correlation spike in the correlation plane. A preliminary investigation of an appropriate figure of merit for comparing correlation spikes produced by different inputs and phase-only filters is also presented. |
