METHOD OF MEASUREMENT OF DIRECTION OF PROPAGATION OF SEA WAVES ROM FLYING VEHICLE AFLOAT Russian patent published in 1997 - IPC

FIELD: location methods of determination of statistic characteristics of state of sea. SUBSTANCE: method provides for irradiation of surface with pulse signals and determination of distance to water surface. Signals are radiated by two receiving-radiating systems positioned at distance less than half-length of sea waves. Accelerometer measures vertical components of accelerations by which translation of receiving-radiating system is found which gives possibility to evaluate ordinates of inherent vibrations of sea surface, probability of various symptoms of these vibrations and mean period. Angle of longitudinal symmetry axis of flying vehicle with regard to direction of propagation of sea waves is calculated by obtained results. EFFECT: increased authenticity. 3 dwg
