Abstract

"Preelaboratore per la rivelazione di sorgenti puntiformi in scenari ripresi nell'infrarosso" essenzialmente costituito da un'interfaccia ingressi (INT1) (1); da un filtro trasversale (FIR) (2); da un dispositivo a soglia adattiva (3) a sua volta costituito da una memoria biporta interna (MEM) (3.1); da un'unità di processamento aritmetico (APU) (3.2); da un insieme di risorse (RES) (4); da un'interfaccia di uscita (INT2) (5), ecc. L'invenzione si colloca nel campo tecnico dei sistemi di sorveglianza in banda IR, più in particolare in quello dell'elaborazione del segnale e può essere utilizzato in sistemi elettronici posti su navi, aerei, elicotteri, mezzi di trasporto, carrarmati, aeroporti e dovunque si ravvisi la necessità di rivelare, da più lontano possibile, eventuali sorgenti artificiali calde e/o naturali. Rispetto alle tecniche precedenti, il preelaboratore varia il tipo di filtraggio, adattando il filtro stesso alla vera forma del segnale IR, puntiforme, che dipende dalle caratteristiche elettroottiche del sensore.
