摘要：

In this paper, we propose a new two-stage Rao test detector, which is obtained by cascading a subspace detector (SD) and the Rao test. A set of secondary data is available and noise returns in primary and secondary data share the same statistical characterization. Analytical expressions for the probability of false alarm (P1 a) and the probability of detection (Pd) are provided in homogeneous environment. Remarkably, the proposed detector possesses the constant false alarm rate (CFAR) property with respect to the noise covariance matrix and the considered examples have highlighted that our detector can ensure better robustness with respect to the counterparts.
