FIELD: oceanographic measurements; information and measurement complexes for determination of static characteristics of sea swell. SUBSTANCE: method is based on sending pulse signal to sea surface and determining the time required for its passing to sea surface. Vertical acceleration of receiving-radiating system is measured with the aid of accelerometer located near the system and then vertical components of speed and corresponding vertical displacement of receiving-radiating system are determined; the magnitudes thus obtained are subtracted from present distance to sea surface. Fluctuations of present magnitudes of mismatch thus obtained is analyzed at preset interval of digitization and root-mean- square value of sea wave height is determined. EFFECT: enhanced accuracy. 1 dwg
