Lidar has the same problems with foggy conditions.
- kajecounterhack 2y agoAgreed, thus the need for radar. Thermal imaging can also see past fog fwiw, though it has other tradeoffs.
- Animats 2y agoActually, no. Look up videos of "range-gated imagers". With multi-hit data for each scan point and appropriate processing, you can see through fog. This technology has been around for years but not talked about much outside military applications.
- bagels 2y agoThanks for that, it makes sense. Same techniques are available in radar. This will give you a higher noise floor and also lower signal if fog sits between you and the subject. It probably does improve the situation over visible light, but only up to a point.
