Beam Divergence vs tall grasses

Beam Divergence vs tall grasses

Currently running a ReconXT, but am struggling to get decent penetration through crops such as wheat and soy beans. In the imagery I can generally see the black dirt, but the LiDAR just doesn't seem to penetrate the plant life.

Current Flight plans
AGL~ 250-350ft.
Speed ~15mph.
SideLap ~55% on the camera... closer to 75% on the LiDAR.

Typical grasses
typical cover
