   Abstract : This thesis presents the design and implementation of a multifunctional radar sensor. Utilising microstrip transmission line technology, a front-end receiver has been designed based upon a six-port architecture. READ MORE

3. 2. Chirp Sounding and HF Application : SDR Technology Implementation

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Dino Dautbegovic; [2012]
   Keywords : SDR; GNU Radio; Ionosphere; Ionosonde; GNU Chirp Sounder;

   Abstract : From a HF propagation point of view, the ionospheric layers act as partially conducting media (plasma) in which a transmitted radio wave can reflect upon.A way of determining whether a radio wave with a given frequency will reflect from the ionosphere or completely penetrate is to utilize special radar instruments know as ionosondes or chirp sounders.

4. 3. Modification of the auroral E-region with powerful HF waves

   University essay from KTH/Rymd- och plasmafysik

   Author : Nicola Schlatter; [2010]
   Keywords : ;

   Abstract : Data from an ionospheric heating experiment in Tromsø have beenanalyzed. The experiment was carried out during auroral conditions inOctober 2006. Beside data from the EISCAT UHF radar also opticaldata were recorded with the ASK (auroral structure and kinetics) instrumentand enhancements of backscattered power from the E-regionwere studied.
