This thesis addresses multi-sensor detection of unmanned aerial vehicles (UAVs) combining radio-frequency, acoustic, and optical modalities. The RF branch uses an ADALM-PLUTO software-defined radio with PSD-based detection in the 2.4 and 5.8 GHz ISM bands, the acoustic branch performs harmonic analysis of the blade-passing frequency on a BM-500 microphone signal, and the optical branch detects motion on a USB webcam using MOG2 background subtraction. A fusion engine combines per-modality confidence scores with exponential temporal decay. The complete Python pipeline with web GUI was validated on outdoor recordings of an FPV quadcopter and on the public DroneRF and Svanström multi-sensor datasets. The reference architecture of a stationary detection station integrating SDR, microphone array, PTZ camera, thermal imager, and Jetson edge computing is proposed for the target deployment.

Process of defence
Student odprezentoval a s drobnými výhradami zodpověděl otázky oponenta. Student potvrdil, že jeho nastavení parametrů pro fúzi dat je provedeno empiricky a přijal výtku, že toto nastavení se nabízí statisticky podložit, případně měnit adaptivně. Práce vyzdvihla, že některé informace v práci jsou mylné, nepravdivé a nepodložené literaturou či experimentem (tedy vymyšlené). Komise se ptala na srovnání s anotovanými datasety.
