Probability of detection for swerling model fluctuating targets with a square-law detector and different signal to noise ratios

In this paper we derive the expressions of the probability of detection for Swerling models of the target when a square law detector is applied on samples with different signal to noise ratios. This is typically the case when the outputs of multiple radar waveforms, having different power budgets and using frequency agility, are noncoherently integrated in a square law detection scheme.
