BAE Systems has delivered the first production Directional Infra Red Countermeasures (DIRCM) anti-missile protection turret. The system is being fitted to transport aircraft and helicopters in service with American and British armed forces and will protect the aircraft from infra red heat-seeking missiles by jamming the seeker ... DIRCM is a revolutionary protection system, which is designed to detect the launch of a heat-seeking missile, determine if it is a threat and track its flight, before defeating its seeker head with an emission of infra red energy. The missile loses its lock on the target and very quickly veers off its course and is destroyed. 2, record 9, English, - DIRCM%20turret

En 1990, Thomson-CSF a introduit la technique Skyhopper, saut de fréquence adaptatif en HF, qui combine l'analyse spectrale automatique et une méthode avancée de traitement du signal, le système Skyhopper a essentiellement pour rôle de rechercher les canaux libres et d’organiser la séquence d’agilité de fréquence en fonction du brouillage naturel ou artificiel. 1, record 10, French, - saut%20de%20fr%C3%A9quence%20adaptatif%20en%20HF

By contrast, the performance of an FM system deteriorates rapidly after falling below a certain threshold. Phase-modulated signals, when properly processed, require less bandwidth and can be coded using pseudo-noise and spread-spectrum techniques, thus reducing the chance of enemy detection. 1, record 12, English, - pseudo%2Dnoise

Les ingénieurs de Hughes ont découvert qu'avec cette méthode l'image de télévision s’affaiblit graduellement à mesure qu'augmente l'intensité du signal de brouillage, alors que les performances d’un système utilisant la technique FM se dégradent rapidement lorsqu'elles sont tombées au-dessous d’un certain seuil. Les signaux modulés en phase, lorsqu'ils sont convenablement traités, exigent une moins grande largeur de bande et peuvent être codés au moyen des techniques de pseudo-bruit et d’étalement de spectre, ce qui diminue les risques de détection par l'ennemi. 1, record 12, French, - pseudo%2Dbruit
