Abstract

Une méthode détalonnage radiométrique de la surface équivalente radar (i) dun nombre N de cibles radar T i, i = 1, 2, ..., N, qui est plus grand ou égal à 3, est décrite. Au moins une cible radar T1 comprend un émetteur radar S1 comprenant une antenne d'émission SA1 et un récepteur radar E1 comprenant une antenne de réception EA1, le récepteur E1 et lémetteur S1 fonctionnant indépendamment, une cible radar T2 comprend un émetteur radar S2 comprenant une antenne d'émission SA2, un récepteur radar E2 comprenant une antenne de réception EA2, et une unité D2, au moyen de laquelle lémetteur S2, en mode de transpondeur TM de la cible radar T2, est branché sur le récepteur E2, de sorte quun signal S reçu par le récepteur E2 soit encore émis par lémetteur S2, et au moyen de laquelle, lémetteur S2, en mode radar RM de la cible radar T2, nest pas branché sur le récepteur E2, de sorte que lémetteur S2 et le récepteur E2 fonctionnent indépendamment.
