Abstract : Resolving targets is formulated as a hypothesis testing problem. A generalized likelihood approach is developed and positive results are obtained. Using a sampling rate of 1.5 samples per pulsewidth, two 20-dB nonfluctuating targets can be resolved at a resolution probability of 0.9 and at a false alarm rate of 0.01, at separations varying between 1/4 and 3/4 of a pulsewidth, depending on the relative phase difference between the targets. The generalized likelihood approach was compared to several easily implemented adhoc approaches, and an ad hoc approach involving fitting a pulse shape to the data is only slightly less accurate than the likelihood approach.
