Der \u00dcbergang von Silizium zu Halbleitern mit breitem Bandgap (Gallium-Nitrid, Siliziumkarbid und andere) erm\u00f6glicht es, die Betriebsfrequenzen erheblich zu erh\u00f6hen und die Effizienz von L\u00f6sungen zu steigern. Daher ist einer der vielversprechenden Anwendungsbereiche f\u00fcr brechbandige Chips und Transistoren die Kommunikation und Radar. Elektronik auf GaN-L\u00f6sungen bietet \"aus dem Nichts\" Leistungssteigerungen und eine Erweiterung der Radarreichweite, was sofort von den Milit\u00e4rs genutzt wurde.<\/p>\n

\"Die<\/p>\n

Lockheed Martin meldete<\/a><\/noindex>, dass die ersten mobilen Radarsysteme (RLS) auf Basis von Elektronik mit Gallium-Nitrid-Elementen an die US-Truppen geliefert wurden. In der Firma wurden keine neuen Entwicklungen erfunden. Die seit 2010 in den Dienst \u00fcbernommenen Gegenschlag-RLS AN\/TPQ-53 wurden auf eine GaN-Basis umgestellt. Dies ist der erste und bisher einzige Radar der Welt, der auf Breitband-Halbleitern basiert.<\/p>\n

Durch den \u00dcbergang zu aktiven GaN-Komponenten hat das Radarsystem AN\/TPQ-53 die Erkennungsreichweite von versteckten Artilleriepositionen erh\u00f6ht und die M\u00f6glichkeit zur gleichzeitigen Verfolgung von Luftzielen erhalten. Insbesondere wird das Radarsystem AN\/TPQ-53 gegen Drohnen eingesetzt, einschlie\u00dflich kleiner Luftfahrzeuge. Die Identifikation versteckter Artilleriepositionen kann sowohl im Sektor von 90 Grad als auch mit einem kreisf\u00f6rmigen 360-Grad-Blick erfolgen.<\/p>\n

Lockheed Martin ist der einzige Anbieter von Radarsystemen mit aktiver Phased-Array-Antenne (FAR) f\u00fcr die US-Streitkr\u00e4fte. Der \u00dcbergang zur GaN-Basis erm\u00f6glicht es dem Unternehmen, auf eine langfristige F\u00fchrungsposition im Bereich der Verbesserung und Herstellung von Radaranlagen zu setzen.<\/p>\n
