Implementation of a low cost demonstrator riometer on a flexible FPGA backend: The first steps in adding a riometer mode to the digital SuperDARN radar at SANAE IV
… base in Antarctica (SANAE IV) and is administered by the South African National Space Association (SANSA). The radar at SANAE IV was recently upgraded to a fully digital transceiver, with the addition of a Field Programmable Gate Array (FPGA) at the core of this upgrade. FPGAs allow for easy …

Design of Software Defined Radio for SuperDARN Radar
… successfully designed and constructed using the Red Pitaya software defined radio. This prototype included a 4 channel receiver which was evaluated in the laboratory setting and tested at the Blackstone, Virginia radar site. A comparison of results from the prototype receiver and the existing …

High frequency surface wave radar demonstrator
… Combined with an SDR platforn known as the Red Pitaya (RP), a complete HF radar demonstrator was assembled and trials were conducted at the UCT rugby field and at the IMT facilities in Simon’s Town. A preliminary assessment of the results reveal the effects of Bragg resonance scatter and …
