METHOD OF MEASURING CHARACTERISTICS OF WAVY WATER SURFACE |
摘要 |
FIELD: physics. ^ SUBSTANCE: disclosed is a method of measuring second order statistical moments of a water surface wave which is greater than the wavelength of acoustic radiation using an acoustic system comprising an acoustic Doppler emitter and three antennae: two receiving antennae with knife-edge patterns and one transceiving antenna with a symmetrical beam pattern. The acoustic system is placed at the bottom or on a fixed underwater platform and emission is carried out vertically upwards. For such a configuration of the measuring system, there are algorithms for restoring second order statistical moments and the effective reflection coefficient. Additional use in the Doppler acoustic system of an antenna with a narrow symmetrical beam pattern also enables to measure the height of the moderate sea and calculate the elevation spectrum. ^ EFFECT: broader functional capabilities and high measurement accuracy. ^ 2 cl, 2 dwg |
