Abstract
We show the effect of multiple scattering on the shape of the pulse returne d by a modulated lidar for bathymetry studies. Multiple scattering lengthen s the tracks of individual photons, and consequently broadens pulse shape d estroying the modulation. However, the reduction of the detector field of v iew allowed us to sharpen the pulses and to restore the modulated signal.
