Abstract
On forme une caractéristique préétablie d'amplification en fonction de la direction ( theta ) d'où proviennent des signaux acoustiques reçus par deux transducteurs (1, 2) acoustiques/électriques distants l'un de l'autre, en déterminant de manière répétitive un signal de retard mutuel (A10) à partir des signaux de sortie des transducteurs et, en fonction du retard de réception au niveau des transducteurs, on filtre l'un (S1) des signaux de sortie, ce qui permet de réguler la caractéristique de transfert du filtrage en fonction du signal de retard mutuel (A12). Le signal de sortie issu du filtrage est ensuite utilisé en tant que signal de réception électrique (Sr).
