You'll want to look at the KrakenSDR. It's basically a circuit board integrating 5 RTL-SDR chips driven from a single clock source and calibrated for phase coherency, for the express purpose of doing radio interferometry amongst other things. They're in stock at Mouser.
- thoop 3y agoWhoa yeah this looks like it would be easier than doing it all by hand. $466 at Mouser. Interesting! Looking around on Google, I don’t see anyone that has tried using this for interferometry yet but the KrakenSDR team explicitly mentions that it can be used for interferometry.
- CamperBob2 3y agoThey were pitching it for use in bistatic passive radar, which is a very similar application, until somebody put the fear of ITAR into them. Some of that code is probably still lying around.
- jesprenj 3y agoI mirrored whatever they had when they got taken down on github: http://ni.4a.si/anonymous/krakensdr_pr/ http://ni.4a.si/anonymous/krakensdr_pr/ The wiki is still public afaik.
