Lockheed Martin rapporterade<\/a><\/noindex>, att de f\u00f6rsta mobila radarinstallationssystemen (RLS) baserade p\u00e5 elektronik med galliumnitridkomponenter har levererats till den amerikanska milit\u00e4ren. F\u00f6retaget har inte kommit p\u00e5 n\u00e5got nytt. De radarsystem av typ AN\/TPQ-53, som antogs i tj\u00e4nst 2010, har nu \u00f6verg\u00e5tt till galliumnitridkomponenter. Detta \u00e4r den f\u00f6rsta och hittills enda radarn i v\u00e4rlden som anv\u00e4nder bredbandiga halvledare.<\/p>\n

Identifieringen av dolda artilleripositioner kan ske b\u00e5de i en 90-graders sektor och med en cirkul\u00e4r 360-graders \u00f6verblick.<\/p>\n

Lockheed Martin \u00e4r den enda leverant\u00f6ren av radar med aktiv phased array (FAR) till den amerikanska milit\u00e4ren. \u00d6verg\u00e5ngen till galliumnitridkomponenter g\u00f6r att f\u00f6retaget kan f\u00f6rv\u00e4nta sig fortsatt l\u00e5ngvarig ledarskap inom utveckling och produktion av radarsystem.<\/p>\n
