I don't see how you can say millimetre wave radar "does the job many times better".
State-of-the art 79 GHz automotive radar: 0.2 m range uncertainty, 5 degree azimuth angular uncertainty, dozens of points per second.
Spinning lidar: <0.05 m range uncertainty, <0.1 degree azimuth angular uncertainty, a million points per second.
Radar definitely has its uses as it can see through weather conditions and tell velocity, but lidar is the vastly superior sensor otherwise.
- baybal2 9y agoLooks 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.
- rmonroe 9y agoSAR 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.
