Hello to the community!
I am interested in building a small Synthetic Aperture Radar System able to provide image information up to 1km away, By "small" I mean something lightweight enough that can be used as a sensor unit on a small-sized unmanned aerial vehicle. I would also like it to be cheap meaning no more than 500$. I am aware of the main principles and know how to deal with the frequency domain calculations but I do not have a clear solution on how to build a small yet effectively working radar system.
Awaiting for your input!
Best,
Kostas
