How the LIDAR tech GM just bought probably works

Looks surprisingly close to specs of a Panasonic made radar.

That is far from what is currently considered advanced for mm-wave radar in 93-95ghz range - 0.5 degrees

Google "GPU Acceleration of SAR/ISAR Imaging Algorithms" and see how much you can get with with regular high bandwidth 10ghz radar and computing power in tenths of gigaflops.

SAR generally relies on assumptions that your target is not changing. I question how well it would work in a complicated environment like a road scene. In my opinion, the single-shot nature of LIDAR is more robust. But its possible that SAR techniques have advanced since my work in it 3 years ago.
