Building the 3D Boundary Environment via Backprojection
To convert the raw pulsed radio waves from the moving drone into a physical 3D map within the SoundThinking environment, Motorola's AI pipelines typically utilize a Time-Domain Backprojection (TDBP) algorithm.

Like fine, I now know that was stupid, but a) I was a child and b) I still think we need to rely on backprojection. In any case, I genuinely thought that my country was safe, and I do think, in some sense, at the time, it still was.

Fixed some bugs in my SAR processing code and now fast factorized backprojection generates a visually identical picture to the normal backprojection, but over 10 times faster. That's huge because normal backprojection was already extremely quick and there's still room for optimization with FFBP.

Found motivation to write some SAR processing code. Fast factorized backprojection generates several small polar format images and then interpolates them to one big image. It's faster, but has slightly worse image quality due to all the interpolations.
