Research on Processing Method of the Airborne Oceanwave Spectrometer Data
摘要
Abstract
The experiment of the oceanwave spectrometer,using wide beam equivalent to satellite antenna,is capable of measuring the backscattering coefficient of the sea surface and retrieving the wave spectrum and wave parameters.The experiment was made in the middle of the Yellow Sea.The radar echo data of small incidence angle was processed and analyzed.Back projection integration was uesed to partly correct the range cell migration caused by the airplane flying and the anttenna rotating.Besides,cross spectral method was used to reduce the speckle noise.Thus,oceanwave spectrum was able to be retrieved in low sea-state.The results show that the measurement of wave spectrum,significant wave height,main wavelength and main wave direction of oceanwave spectrometer were consistent with those of synchronous buoy and optical satellite measurements.关键词
