Other AbstractIn order to study the feasibility of ocean surface current measurement using radar scatterometer, the system parameters of the traditional scatterometer were modified, the coherent coefficient model and decorrelation factors were derived, and the phase error model was obtained. Moreover, this paper established an end-to-end model to simulate the ocean surface current measurement. The input wind speeds ranged from 2m/s to 21m/s and the wind direction was parallel to the cross track direction. The results show that the current speed standard deviation in along-track and cross-track direction are smaller than 0.1m/s, when the wind speed is greater than 5m/s. And the swath that can be used for current speed inversion is greater than 40%, when the wind speed is larger than 7m/s. The width of effective swath increases with the increase of the wind speeds. After parameters' optimization, communication error was calculated and the results show that the communication error of the modified scatterometer is better than that of the fan-beam, rotating scatterometer in both the low wind speed and high wind speed conditons. ©, 2015, Chinese Institute of Electronics.
