The paper presents the possibilities of,and methods for,acquiring,analysing and processing optical signals in order to recognise,identify and counteract threats on the contemporary *** main ways electronic warfare is waged in the optical band of the electromagnetic wave spectrum have been formulated,including the acquisition of optical emitter signatures,as well as ultraviolet(UV)and thermal(IR)*** physical parameters and values describing the emission of laser radiation are discussed,including their importance in terms of creating optical ***,it has been shown that in the transformation of optical signals into signatures,only their spectral and temporal parameters can be *** was confirmed in experimental part of the paper,which includes our own measurements of spectral and temporal emission characteristics for three types of binocular laser *** has been further shown that through simple registration and quick analysis involving comparison of emission time parameters in the case of UV signatures in“solar-blind”band,various events can be identified quickly and *** same is true for IR signatures,where the amplitudes of the recorded signal for several wavelengths are *** was confirmed experimentally for UV signatures by registering and then analyzing signals from several events during military exercises at a training ground,namely Rocket Propelled Grenade(RPG)launches and explosions after hitting targets,trinitrotoluene(TNT)explosions,firing armour-piercing,fin-stabilised,discarding sabots(APFSDS)or high explosive(HE)*** final section describes a proposed model database of emitters,created as a result of analysing and transforming the recorded signals into optical signatures.
