Abstract:

The pulsed lidar return power used for sounding a random-rough surface by means of a narrow laser beam is studied. Analytic expressions for the echo signal delay and broadening are derived for the case where the shadowing effect is neglected. For the divergence angles comparable with rms slopes of the surface micropatches, the lidar pulse duration is shown to reduce dramatically both in a clear and turbid aerosol atmosphere.
