    Keywords : Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

    Abstract : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. READ MORE

  4. 3. Improving deep learning assistedfar-field electromagnetic sidechannelattacks on AES : Effects on attack efficiency from using additive noise and otherdata augmentation techniques

    University essay from KTH/Mekatronik

    Author : Axel Zedigh; [2022]
    Keywords : ;

    Abstract : Profiled side-channel attacks on hardware implemented cryptographic algorithms have been a well-researched topic for the past two decades and many countermeasures against these attacks have been proposed and adopted by the industry. Recently, a new form of far field EM side channel called "screaming channel attacks" have been highlighted. READ MORE

  6. 5. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    University essay from KTH/Fastigheter och byggande

    Author : Adrien Bardou; [2021]
    Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.
