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 sigma0(thetai) and sigma0(thetai+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 sigma2 i(&phis;j). The total dispersion of inclinations sigma2 i for "i"-th elementary dissipating particles is determined and direction of propagation &phis;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[sigmao, sigma2 i(&phis;j), sigma2 i(&phis;j+90°)] calculated by standard regression method. ^ EFFECT: improved efficiency of monitoring from board of satellite. ^ 3 cl, 6 dwg |
