FIELD: physics.
SUBSTANCE: sea surface is vertically probed by a pulse laser, the reflected pulses are recorded and the dispersion of sea surface slopes is calculated based on them. Preliminarily the significant height of waves hs is defined, the minimum duration of the probing pulse τm is calculated from condition τm= 4hs/c, where c is the speed of light. Taking into account the obtained value τm probing pulses of the calculated duration are formed and the sea surface is probed with such pulses.
EFFECT: increasing the accuracy of determination of sea surface slope determination.
