Abstract :
This paper deals with the problem of detecting a signal known up to a scaling factor in the presence of Gaussian disturbance with unknown covariance matrix. We propose a novel derivation of the adaptive matched filter (AMF) previously designed in a previous paper by Robey et al.. Precisely, we show that the Wald test for the problem at hand coincides with the AMF.
