How deep can lidar penetrate ground

http://global-gpr.com/gpr-technology/how-gpr-works.html WebIn heavily vegetated areas LIDAR systems can be challenged to locate the ground surface. Most LIDAR systems use a near-infrared laser that does not penetrate fog or rain. (Fowler 2001) INSAR bypasses some of these problems. Flying higher and faster than most LIDAR systems, an INSAR-equipped plane can cover large areas.
