Abstract

The effect of sea waves on the characteristics of bathymetric lidars is studied. The main effects responsible for the distortion of bathymetric information are discussed. The displacement of the sounding beam and its broadening in a horizontal plane, the statistical mean variation in the signal’s delay time, the variance of signal arrival times, and the increase in the duration of the received signal are evaluated. The calculations are performed allowing for the absorption and multiple scattering of light in water.
