Analysis of Velocity Measurement Error for Future Geostationary Spaceborne Doppler Weather Radar

Geostationary Spaceborne Doppler weather radar (GSDWR) is a conceptual radar proposed by NASA and it was expected to improve the monitoring and predication of hurricanes or typhoons. In order to analyze the velocity measurement error of GSDWR, echo power spectrum is simulated. The paper analyses the velocity measurement error of GSDWR from two aspects: the characteristics of power spectrum and the accuracy of velocity measurement.
