Direction detection is aimed at discriminating, over multiple "snapshots,"between a disturbance-only hypothesis and a useful-signal plus disturbance alternative with useful signals modeled in terms of a common (i.e., over different snapshots) direction of the signal subspace. We will show that generalized-likelihood ratio test (GLRT)-based direction detectors, designed assuming Gaussian noise with unknown covariance matrix plus deterministic interference, belonging to a preassigned subspace of the observables, possess the constant false alarm rate property with respect to the unknown covariance matrix of the noise

Abstract
Direction detection is aimed at discriminating, over multiple "snapshots,"between a disturbance-only hypothesis and a useful-signal plus disturbance alternative with useful signals modeled in terms of a common (i.e., over different snapshots) direction of the signal subspace. We will show that generalized-likelihood ratio test (GLRT)-based direction detectors, designed assuming Gaussian noise with unknown covariance matrix plus deterministic interference, belonging to a preassigned subspace of the observables, possess the constant false alarm rate property with respect to the unknown covariance matrix of the noiseFile in questo prodotto:
