Deception has long been a central component of Russian warfare, a fact that has become evident in modern conflicts where the state has been involved, not least during the annexation of Crimea in 2014. After the armed conflict, an unstable period unfolded in several Ukrainian regions, as well as in the adjacent maritime areas of the Black Sea and the Sea of Azov. Russia’s aggressive behavior in the sea regions was driven by a goal of dominance, manifested through multifaceted actions that included both conventional and unconventional methods. A gray zone conflict was launched in the maritime domains. Existing research studying Russia’s naval warfare has paid only limited attention to use of deception, which means it misses a key aspect of its on-sea activity. With the aim to contribute more broadly to research on Russian naval warfare, this study has used a theory of deception to describe how and when the state has employed methods related to the phenomenon in the gray zone conflict. The result of the analysis shows that Russia, in its multidimensional conduct across the broad spectrum between war and peace, has utilized deception methods in various instances, with an increased intensity in the year preceding to the conflict’s escalation into full-scale war.

I efterbörden av Rysslands annektering av Krim 2014 uppstod diskussioner kring rysk krigskonst och hybridkrigföring. Bland tvetydigheterna som uppstod identifieras bland annat vilka strategier som det samtida Ryssland har för att uppnå strategisk överraskning. Denna studie har syftat till att undersöka rysk militär vilseledning i samband med Rysslands strategiska överraskningsanfall på Krim 2014. Studien har genomförts som en teoriprövande fallstudie varvid såväl västerländska som sovjetiska/ryska vilseledningsteorier prövats på det ryska agerande under annekteringen av Krim 2014. Sammantaget visar studiens resultat på förekomster av ryskt agerande i enlighet med samtliga av studiens prövade teorier varvid det i huvudsak var distraktion, dolda aktiva åtgärder samt desinformation som bidrog till den ryska strategiska överraskningen. Studiens oväntade resultat pekar på ett aktivt deltagande av den ryske presidenten personligen varvid det inte går att underskatta betydelsen av en politisk företrädare som Vladimir Putin. Studiens resultat kan vidare tolkas som att den vilseledning som Ryssland genomförde får ses vilande i huvudsak på tidigare dokumenterade sovjetiska teorier. Vidare visar studiens resultat på en hög rysk förmåga till anpassning där tidigare etablerade sovjetiska/ryska teorier kring vilseledning utvecklats till dagens konfliktmiljöer. Studien visar därmed att äldre sovjetiska/ryska teorier på inget sätt är obsoleta utan i allra högsta grad fortsatt är aktuella i dagens globala världsordning. / In the aftermath of Russia's annexation of Crimea 2014, discussions arose about Russian military art of war and hybrid warfare. Questions were identified regarding strategic surprise and what strategies todays’ modern Russia was using. This study aims to investigate Russian military deception in connection with Russia's strategic surprise attack in Crimea 2014. The study was conducted as a single case study in which Western as well as Soviet/Russian theories of military deception was compared with the Russian activities during the Crimea annexation in 2014.  The result shows Russian activities in accordance with both Western and old Soviet/Russian theories of deception. According to the study Russian main focus was distraction, active measures and disinformation leading to the Russian strategic surprise. The study shows unexpected results regarding the amount of personal activity involving the Russian president, Vladimir Putin. The result shows that the significance of a political representative such as Vladimir Putin cannot be underestimated. Additionally the study also shows that the military deception conducted by Russia in and around the period of the Crimea annexation 2014 mainly extracts from previously documented old Soviet theories. It highlights Russia’s ability to adapt into today's conflict environments by bending and adjusting old theories and doctrines. By that meaning old Soviet/Russian theories are in no way obsolete but instead being very much relevant in today's global world order.

In this work, the interference sensitivity of an FMCW radar has been evaluated by studying the impact on a simulated detection chain. A commercially available FMCW radar was first characterized and its properties then laid the foundation for a simulation model implemented in Matlab. Different interference methods have been studied and a selection was made based on the results of previous research. One method aims to inject a sufficiently large amount of energy in the form of pulsed noise into the receiver. The second method aims to deceive the radar into seeing targets that do not actually exist by repeating the transmitted signal and thus giving the radar a false picture of its surroundings. The results show that if it is possible to synchronize with the transmitted signal then repeater jamming can be effective in misleading the radar. In one scenario the false target even succeeded in hiding the real target by exploiting the Cell-Averaging CFAR detection algorithm. The results suggests that without some smart countermeasures the radar has no way of distinguishing a coherent repeater signal, but just how successful the repeater is in creating a deceptive environment is highly dependent on the detection algorithm used. Pulsed noise also managed to disrupt the radar and with a sufficiently high pulse repetition frequency the detector could not find any targets despite a simulated object in front of the radar. On the other hand, a rather significant effective radiated power level was required for the pulse train to achieve any meaningful effect on the radar, which may be due to an undersampled signal in the simulation. It is therefore difficult based on this work to draw any conclusions about how suitable pulsed noise is in a non-simulated interference context and what parameter values to use.
