Abstract
In this paper, the distribution of the test-statistic for the covariance based detection (CBD) is studied in order to obtain the mathematical expressions of false alarm probability (Pf) and detection probability (Pd) . The formulation of decision threshold λ for any Pf is also presented. The expression of Pd allows to evaluate the performance of the CBD technology. Finally, the decision threshold, as well as the derived Pf and Pd , is verified with Monte-Carlo simulations.
