Abstract

Ometanje radara obmanjivanjem je sofisticirana tehnika koja se koristi u vojnim operacijama za zaštitu aviona, brodova i drugih sredstava od neprijateljskih radarskih sustava. Ova tehnika funkcionira tako da zbunjuje radarski sustav, otežavajući mu točno otkrivanje, praćenje ili identificiranje stvarnih objekata. Emitiranjem lažnih signala koji oponašaju stvarne ciljeve, radarskim operaterima se prikazuje slika koja nije vjerodostojna, stvarajući iluziju prisutnosti više ciljeva ili promijenjenih položaja stvarnih objekata. Ponavljanje i modifikacija radarskog signala dodatno kompliciraju situaciju, jer se radaru vraća signal koji je izmijenjen tako da stvori pogrešne podatke o udaljenosti, brzini i smjeru kretanja cilja. Cilj ovih metoda je obmanjivanje neprijateljskih sustava, čime se povećava šansa za izbjegavanje detekcije i napada, omogućujući sigurniji prolaz kroz neprijateljski prostor i zaštitu vojnih resursa. Ometanje radara obmanjivanjem ključni je element u modernom ratovanju, koji se neprestano razvija kako bi odgovorio na sve sofisticiranije radarske tehnologije.

Abstract (english)

Radar jamming and deception is a sophisticated technique used in military operations to protect aircraft, ships and other assets from enemy radar systems. This technique works by confusing the radar system, making it difficult for it to accurately detect, track, or identify real objects. By emitting false signals that mimic real targets, radar operators are presented with an image that is not credible, creating the illusion of the presence of multiple targets or changed positions of real objects. Repetition and modification of the radar signal further complicates the situation, because the signal returned to the radar has been modified in such a way as to create erroneous data on the distance, speed and direction of the target. The goal of these methods is to deceive enemy systems, thereby increasing the chance of avoiding detection and attack, enabling safer passage through enemy space and protection of military resources. Radar jamming through deception is a key element in modern warfare, which is constantly evolving to respond to increasingly sophisticated radar technologies.
