\"Armata<\/p>\n

Compania Lockheed Martin a declarat<\/a><\/noindex>, ceea ce a dus la livrarea primelor unit\u0103\u021bi mobile de radare (RLS) bazate pe electronica cu elemente din nitrur\u0103 de galiniu c\u0103tre trupele statelor Unite. Nu s-au inventat nimic nou \u00een cadrul companiei. Radarul de contrabaterie AN\/TPQ-53, adoptat \u00eencep\u00e2nd din 2010, a fost transformat pentru a utiliza baza de elemente GaN. Acesta este primul \u0219i, p\u00e2n\u0103 \u00een prezent, singurul radar din lume bazat pe semiconductori cu band\u0103 larg\u0103.<\/p>\n

Datorit\u0103 trecerii la componentele active GaN, radarul AN\/TPQ-53 a \u00eembun\u0103t\u0103\u021bit raza de detec\u021bie a pozi\u021biilor de artilerie \u00eengropat\u0103 \u0219i a c\u00e2\u0219tigat capacitatea de a urm\u0103ri simultan \u021binte aeriene. \u00cen particular, radarul AN\/TPQ-53 a \u00eenceput s\u0103 fie folosit \u00eempotriva dronelor, inclusiv a aparatelor mici. Identificarea pozi\u021biilor de artilerie \u00eengropat\u0103 poate fi efectuat\u0103 at\u00e2t \u00een sectorul de 90 de grade, c\u00e2t \u0219i cu o vizibilitate circular\u0103 de 360 de grade.<\/p>\n

Compania Lockheed Martin este singurul furnizor de radare cu Faza Activ\u0103 (antena cu fazare) pentru trupele Statelor Unite. Trecerea la o baz\u0103 de elemente GaN \u00eei permite s\u0103 se a\u0219tepte la o continuare a pozi\u021biei sale de lider pe termen lung \u00een domeniul dezvolt\u0103rii \u0219i produc\u021biei instalatiilor radar.<\/p>\n
