FIELD: instrumentation.
SUBSTANCE: spacecraft altimeter is used to irradiate water surface so that reflected signal can be registered. Radio pulse front is used to determine the surface wave significant height. Time of signal transmission to and from water surface defines a surface large-scale relief. Said relief is used to calculate surface stream field and to define wind velocity by reflected signal magnitude with due allowance for wave height and stream field effects on reflected signal.
EFFECT: allowance for surface stream contribution into level of radio signals reflected from water surface to increase the wind velocity determination accuracy.
