RADIOLOCATION METHOD FOR DETERMINING PARAMETERS OF CONDITION OF SURFACE-ADJACENT OCEAN LAYER FROM A SATELLITE Russian patent published in 2004 - IPC

FIELD: radiolocation technologies.

SUBSTANCE: method includes orientation of knife-edge pattern along direction of satellite flight, probing impulses are sent to ocean surface into nadir and by each impulse a spot is lit on measured surface with dimensions of about 10-15x200-300 km, and during receiving of reflected impulses temporary and Doppler selection on basis of distance is used as well as procedure of synthesizing of cross-section of backward scattering ς_0y, while dispersion of slants ς2θ

of ocean surface in direction of flight is determined from an equation: where δ - width (in degrees) of directional pattern at level 0.5 of power, ς_0,max - cross-cut of backward scattering during vertical fall of flat wave onto surface, ς_0y - backward scattering cross-cut, received during said synthesizing, and specified speed value V of surface-adjacent wind is determined from one-parameter algorithm with consideration of dispersion ς2θ of slants.

EFFECT: wider set of ocean parameters measured from space.
