You can't filter out what LiDAR can't penetrate... ie water.
Driverless cars have a new way to navigate in rain or snow
May be "filter" is a wrong word.
The algorithm differentiates patterns of bouncing back rays coming from a snow flake or a drop of rain versus an obstacle.
Specialty LIDAR does see through water to determine water depths and 3-d map an ocean floor:
"Bathymetric lidar is used to determine water depth by measuring the time delay between the transmission of a pulse and its return signal."
