Abstract
A bank of matched filters are employed to impose on a transmitted pulse, as well as the optimum matched filter receiver response, exact amplitude and phase modulations necessary to maximize the likelihood of accurate target identification. This is accomplished by subjecting the output of each matched filter (corresponding to a target signature) to a threshold level detector to eliminate identification outputs caused solely by noise. The outputs from the threshold device represents the target identification from each matched filter. Since each matched filter corresponds to a particular target, the highest output identification signal will indicate the presence of a corresponding target.
