PANORAMIC RADAR METHOD OF DETERMINING CONDITION OF OCEAN'S LAYER SURFACE FROM SATELLITE Russian patent published in 2006 - IPC G01S13/95 

FIELD: radar engineering.

SUBSTANCE: method can be used for measuring parameters of sea storm; it can be also used in meteorology and oceanology for distant probing of surface layers of oceans from board of satellite. Microwave range probing pulses are irradiated by Doppler radar. Probing pulses are directed to surface of ocean in nadir; any pulse irradiates spot with sizes of 14x355 km on water surface. When receiving reflected pulses, time and Doppler range selection is used simultaneously inside spot of 14x355 km for elementary dissipating particles with sizes of 14x14 km. Then cross-sections of back dissipation σ0(θ_i) and σ0(θ_i+1) are determined for any two sequent "I"-th and "i+1"-th elementary dissipating particles. The cross-sections correct and determine dispersion of inclinations σ² _i(φ_j). The total dispersion of inclinations σ² _i for "i"-th elementary dissipating particles is determined and direction of propagation φ_wi of large-scale storm in "i"-th elementary dissipating particle is found. Speed V of surface wind is found by means of algorithm f V=F[σ_o, σ² _i(φ_j), σ² _i(φ_j+90°)] calculated by standard regression method.

EFFECT: improved efficiency of monitoring from board of satellite.
