Instructions on obtaining raw phase history data are in the video description.

Is there an approach to generate the imagery using Blackman-Harris windowing (instead of rectangular) to eliminate the cross artifacts?

Fast backprojection is conceptually a simple algorithm, but getting the details right is complicated enough that people have to spend a lot of money/time on it. So, yes, I do know a lot about fast backprojection but no, I can't share anything :(

Very nice. Can I get the raw data (I, Q) ?
