Lidar is solidly worse than the human eye in dust, rain etc. Waymo has struggled w/ dust devils in AZ. Cruise has struggled w/ steam vents in SF. I work at a John Deere subsidiary and we are quite interested in dust performance for field work. From our tests Lidar is low on the list for seeing through small particles.

Lots of things could fix this, less beam divergence, custom signals processing on multiple returns. But out of the box, it’s this statement does not hold true.

I work at an industrial plant we use microwave radar based imaging can get quite detailed surface profiles in very poor conditions including inside reactors etc where dust is big issue. I'm not expert in this field I think systems used are continuous wave based.

For vehicle applications specifically probably worth looking into what they use on autonomous vehicles at mine sites imagine that tech probably useful in agriculture. For example Pilbara here in Australia large autonomous fleets in very dusty conditions.

Hi, I've previously been to a company that makes the hardware for autonomous mining vehicles. They rely mainly on DGPS systems for positioning and a combination of simple camera vision and radar for obstacle detection. Keep in mind they don't drive that fast (around 25 mph), are supposed to be in clear unobstructed (unless they're in a queue to load or unload) and just stop when they detect a vehicle or a person.
