  4. 3. Locating Unknown Wireless Devices Using Stimulated Emissions and the Fractional Fourier Transform

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Per Gustafsson; [2013]
    Keywords : radar measurements; ranging; noncooperative receiver; counter-IED; fractional Fourier transform;

    Abstract : Unknown wireless devices that use receiver architectures with a mixer may be detected and located using stimulated emissions. Transmitting a known stimulation signal and correlating leaked mixer products allows measurement of the TOF and thus range. READ MORE
