Shell script (Ash & Bash compatible) to measure Red Pitaya CPU temperature from Terminal.
How to startup Red Pitaya with a blank SD card.
Pavel Demin’s custom Red Pitaya image on a micro SD card runs HPSDR six receivers simultaneously.
It’s best to do quick tests very early in the project to detect unknowns that might take some time to fix, or even lead to different hardware choices.
Narrowband radar on lowband VHF (25-50 MHz) seems possible via simulation and initial measurement. Subspace methods are necessary due to narrow frequency sep...
Many nations have license free spectrum slices up to hundreds of kHz wide in the 25-60 MHz range. These frequencies can be exploited for short range, humanit...
Particularly with software-defined-radio, it has become feasible for electronics enthusiasts and engineering students to build their own radar. Here are a fe...
Red Pitaya is a dual-DAC + dual-ADC 125 MHz + Zynq FPGA/CPU singleboard SDR powerhouse for <$200. Here’s how to get quick radar measurements.
Measuring the ionosphere with HF radar requires sensitivity to avoiding interference to critical services also using HF.
MIT Lincoln Lab has been using an HF experimental license WH2XBH with transmitter located at Haystack.
The thought of FMCW or DSSS radars operating at HF might initially seem frightening, but such radars are sharing HF in increasing numbers.
The simplest waveform a radar can use is a continuous unmodulated tone. Here is an example GNU Radio-based CW software defined radar using Red Pitaya.
Calibrating a radar requires controlled conditions. That’s very difficult at HF, so we can use low-band VHF with the procedure and material described.
FCC regulations allow operating license-free at low-band VHF, which is relatively uncluttered these days.
When you need a point target in high clutter environments, a radar transponder is good to consider. Here’s how to make a software-defined transponder.
Essential verification of radar system elements can take place separately at a distinct frequency to save cost and time.
Planning has been ramping up in the past year for the Aug. 2017 Solar Eclipse cutting across the United States. PiRadar and TEC instruments are being modeled.
You need Pavel Demin’s custom Red Pitaya image on a micro SD card to run PiRadar code.
You need Pavel Demin’s custom Red Pitaya image on a micro SD card to run the NMR pulsed transmission code.
You need Pavel Demin’s custom Red Pitaya image on a micro SD card, and GNU Radio on your PC to start.
Having received our Red Pitaya pair for PiRadar prototyping, we are delighted to see the educational pricing is favorable.
We are delighted to announce our project team for the open source aeronomy radar has been selected and assembled.
