Test arrangement for a laser threats identifying system of an aircraft

Abstract

A test arrangement for a laser threats identifying system of an aircraft comprises optical detecting means (), adapted to pick up threat light beams (B) impinging on the aircraft () from a plurality of surrounding space sectors, and a threat warning unit (), adapted to receive a plurality of actual optical signals indicative of at least one of the threat beams (B) through a plurality of optical channels (), and arranged for comparing the actual signals with a predetermined library of reference optical signals representing known threats. The test arrangement includes a light emitting source (L) arranged for selectively generating a plurality of predetermined optical signals for simulating virtual threats (S-Sn), and a plurality of optical guides (F-Fn) for the simulation signals (S-Sn), directly coupled with the source (L) and adapted to be connected to the aforementioned optical channels (_n) for selectively stimulating the threat warning unit ().
