Abstract
Un radar di sorveglianza secondaria virtuale (VSSR), "virtual secondary surveillance radar" del tipo descritto nel brevetto statunitense No. 4.115.771 può produrre informazioni di distanza inaccurate o indeterminate per un trasponder posizionato su, o vicino a, una retta tra il SSR reali e il VSSR, a causa di sfavorevoli relazioni geometriche. Questo può essere evitato ricevendo i segnali di interrogazione e di replica del SSR a due o più posizioni separate e elaborando i segnali informazioni di posizione ad un posto di visualizzazione. Non è richiesta alcuna trasmissione radar oltre quelle degli ATCRBS esistenti.
