Abstract
Experiments on sensing of the sea bottom in shallow waters were carried out with an airborne lidar. To reduce glint reflections from the sea water surface in lidar returns, the axial region of the receiving lidar telescope was screened by a shadow field stop. In this case, the entire lidar return from water depth is formed only by multiply scattered radiation. This lidar configuration improves the contrast of signals reflected from the sea bottom.
