A two-color infrared warning device, having both wide-angle and narrow-angle search capabilities, and a directional countermeasure device are mounted on a gimbal pointing in the same direction. The warning device and gimbal are initially operated in a wide-angle, step-stare mode to search for threats. When a potential hostile target is found, the warning device changes to a narrow-angle mode to determine whether the potential target is hostile. When a hostile target is identified, the directional counter-measure device, which is pointed at the target by virtue of its mounting with the warning device on the gimbal, is activated.
L'invention concerne un dispositif d'alarme infrarouge bicolore, doté à la fois de caractéristiques de recherches à grand angle et à angle étroit, et un dispositif de contre-mesure directionnel montés sur un cardan orienté dans la même direction. Le dispositif d'alarme et le cardan sont initialement exploités selon un mode </= step-stare >/= (avance et observation) à grand angle pour détecter les objets menaçants. Lorsqu'une cible hostile potentielle est localisée, le dispositif d'alerte bascule en mode angle étroit pour déterminer si cette cible potentielle est réellement hostile. Lorsqu'une cible hostile est identifiée, le dispositif de contre-mesure directionnel, lequel est orienté sur la cible en raison de sa disposition avec le dispositif d'alarme sur le cardan, est activé.
