Peculiarities of designing pulse laser altimeter to measure the aircraft height above the sea surface are considered. An optimal receiving system used for surface-reflected signal detection takes into account the random characteristics of the surface at various angles of sounding laser beam incidence depending on the aircraft roll and pitch as well as random amplitude of reflected pulses. Recommendations are formulated for choice of sounding pulse repetition rate and emitted energy at a given time constant of height measurement.
