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
… demonstrator riometer is developed using the Red Pitaya FPGA platform as its backend, and tested at the University of Cape Town, at SANSA in Hermanus and at Fish Hoek. A riometer measures the opacity of the ionosphere with respect to cosmic radiation. Doing this over a wide band of frequencies …

Design of Software Defined Radio for SuperDARN Radar
… 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 …

OCRA : a low-cost, open-source FPGA-based MRI console capable of real-time control
… this console. For hard- ware, OCRA uses the Red Pitaya, a commercially available Zync SoC board with a dual-core ARM CPU and Xilinx FPGA. The functionality of the console has been demonstrated on the MGH/MIT Tabletop scanners [2] developed in 2014 and used in MIT courses to teach students about …

Modelling and resolving of the ambiguous angle of arrival measurements of the SANAE IV SuperDARN Radar
… system on an FPGA platform known as the Red Pitaya. Operating parameters are specifically chosen to be consistent with the SANAE IV radar. An antenna arrangement consisting of two receivers and a transmitter is constructed to replicate the AOA issue experienced by the SANAE radar. Instead of …

Characterization of dragon fruit (Hylocereus spp.) components with valorization potential
Dragon fruit (Hylocereus spp.), also known as pitaya or pitahaya, is increasingly gaining interest in many countries, including Thailand which is a country with a climate ideal for breeding different varieties of tropical and subtropical fruits in general, and dragon fruit more specifically. The …
