Re: Potential GSoC contributor introduction and new project idea

Hey Marcus,

Thanks for replying.

I haven't had the opportunity to try out those OOT modules just yet but i did looked into the gr-radar, the UI is similar to what i have in mind, this will be really helpful.

Are there any repo that goes into generating flowgraphs from a GUI?

Regards,

Rahul

Hi Rahul, hi Andrej,

Ettus' gr-doa[0] is a bit stale, not sure it still builds; maybe also check out Marcin's
gr-aoa[2].
And, of course, don't hesitate to check out gr-radar[3] for ideas on visualizations,
though that hasn't been updated to build with modern GNU Radio, either. I think the
radioconda version of gr-radar *does* build with GNU Radio 3.10 (Haven't tested it though).

Best,
Marcus

This tool would support various array configurations (ULA, URA, circular, hexagonal, etc. and possibly custom config??) and implement popular beamforming and DoA estimation algorithms. My vision is to create something similar to MATLAB's Phased Array System Toolbox, but fully open-source and tightly integrated with GNU Radio.

Right now it is not immediately clear to me, where GNU Radio comes in for the GUI for array processing. But figuring out what your project is about is also the goal of developing your proposal with the community.

Would the GUI tool be to visually set nulls & peaks in a antenna diagram and the tool will then provide the parameters for the array processing algorithm?
