Abstract
Aim of the paper is to design a system capable of detecting unmanned aerial vehicles utilizing radio communication sensing. The need to detect UAVs is caused by combination of their compact size, sensing capabilities, autonomous nature, ways of misusing them or their spread among unprofessional users unaware of their own risky handling of UAV. All these factors can lead to serious security threats and risk to human lives or infrastructure. In this paper, radio communication detection system is proposed as part of a robust system where radio detection is supplemented by other methods, to maximise probability of UAV detection. Significant attention was dedicated to deeper analysis of current progress in the area of radio communication detection systems as well as acoustic, visual and radar detection. Based on this analysis, all systems were compared together based on probability of detection and distances of detection. Comparation together with different properties of detection methods were basic stepping stone for final system proposal. Robust detection system was successfully designed with radio detection as its primary component, radar detection serving primarily as localizer of UAV, acoustic system serving as backup for detection of UAVs without radio communication and visual system for final confirmation of UAV, its model and presence of camera or load

Summary
Na základe poznatkov z teoretickej časti sa práca zamerala na analýzu rádiofrekvenčnej detekcie a rovnako alternatívnych metód. Cieľom analýzy je akumulácia dát a informácií dostatočných pre hlbšie porovnanie rádiovej metódy a alternatívnych metód detekcie. Pre účely práce boli zvolené triedy C0, C1 a C2, ktoré sa radia do prevádzkovej kategórie A1, A2 a zahŕňajú UAV od 0 g až do 4 kg. V rámci skúmania prác a dát sa práca zamerala aj na to, v akom prostredí boli vykonané merania. Práca sa ďalej venovala vyhodnoteniu každej metódy detekcie, na základe zozbieraných dát. Posledná časť práce mala v prvom kroku za cieľ porovnať metódy detekcie na základe získaných dát o pravdepodobnosti detekcie UAV a vzdialenosti, na ktorú sú systémy schopné UAV efektívne detegovať. Porovnanie je vykonané na základe aritmetického priemeru hodnôt pravdepodobnosti, ktoré autori prác dosiahli pri konkrétnych vzdialenostiach detekcie. Následne opierajúc sa o informácie z predošlých krokov bol navrhnutý robustný systém detekcie UAV, kombinujúci všetky metódy s cieľom maximalizovať pravdepodobnosť detekcie UAV
