1. A method to identify and remove a false detection comprising: receiving a detection from a constant false alarm rate (CFAR) processor; performing a first similarity measure on adjacent coherent integration time values (CITs) corresponding to the detection; performing a second similarity measure on neighbor CITs corresponding to the detection; determining if at least one of the first or second similarity measure is below a threshold; and discarding the detection if at least one of the first or second similarity measures is below the threshold.
