False Alarm Regulation for Off-Grid Target Detection With The Matched Filter

In the state-of-the-art, the Probability of False Alarm (P F A)threshold relationship for the popular Matched Filter (MF) is often derived assuming that unknown non-linear parameters lie on a grid. However, these parameters vary continuously in…

Sur la probabilité de détection du filtre adapté pour la détection distance-Doppler de cibles hors-grille

Dans la plupart des cas, le filtre adapté est évalué pour des valeurs de paramètres de cibles non-linéaires fixées sur une grille discrète, de manière à avoir des tests statistiquement indépendants. En réalité, les paramètres de cibles appartiennent…
