Asymptotically Optimal CFAR Detectors

This paper investigates the asymptotic optimality of the Constant False Alarm Rate (CFAR) tests obtained using the Minimal Invariant Group (MIG) reduction. We show that the CFAR tests obtained after MIG reduction using the Wald test is a Separating Function Estimation Test (SFET) and that the Generalized Likelihood Ratio Test (GLRT) and the Rao test are asymptotically SFET using Maximum Likelihood...
