3. 2. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Khan Fazal Ullah; [2010]
   Nyckelord :Aperture; Adaptive Line Enhancement ALE ; Chirp signal; Global BackProjection GBP ; Pulse compression; Radio Frequency Interference RFI ; Synthetic Aperture Radar SAR ; UltraWide Band UWB ;

   Sammanfattning : Synthetic Aperture Radar (SAR) has many applications within ground image sensing and navigation. UltraWide Band(UWB) SAR operating at Ultra High Frequency /Very High Frequency(UHF/VHF) are usually a ffected by the Radio Frequency Interferences(RFI) from civilian communication bands which causes SIR(Signal to Interference Ratio) to go down.

4. 3. The Impulse-Radiating Antenna

   Master-uppsats, Fakulteten för teknik- och naturvetenskap

   Författare :Johanna Rosenlind; [2009]
   Nyckelord :Broadband antenna; IRA; time domain simulations; impedance matching; electrical breakdown; CST Microstripes; intentional electromagnetic interference; IEMI; ultrawide band; UWB; high-voltage; pulses;

   Sammanfattning : As the interest in intentional electromagnetic interference (IEMI) increases, so does the need of a suitable antenna which endures those demanding conditions. The ultrawideband (UWB) technology provides an elegant way of generating high-voltage UWB pulses which can be used for IEMI. LÄS MER
