    Interference source single satellite location method based on movable antenna with spot beam by Xijian ZHONG, Gengxin ZHANG, Zhidong XIE

    Published 2016-09-01
    “…An interference source single satellite location method based on movable antenna with spot beam was proposed for GEO satellites.In this method,a mapping relationship between orientation of interference and antenna gain is first established with the function of antenna pattern.Equations were established to calculate the interference signal link combining the orientation information of center of movable spot beam and the intensity of interference signal which derived from moving the beam several times.The orientation of interference was obtained by solving the equations with the help of particle swarm optimization(PSO).Then the longitude and latitude of the interference source could be calculated,jointly considering the ephemeris and the information of the earth.We made a positioning simulation of the ground interference source with the proposed method.The results validate the effectiveness of this method.…”

    C-SAR/02 Satellite Polarimetric Calibration and Validation Based on Active Radar Calibrators by Yanan Jiao, Fengli Zhang, Xiaochen Liu, Zhiwei Huang, Jingwen Yuan

    Published 2025-01-01
    “…This approach improved the accuracy of the polarimetric calibration results and the effect of the quantization application of the C-SAR satellites. Moreover, our experimental results indicate that the method presented herein is suitable for the C-SAR/02 satellite and may also be more universally applicable to C-SAR-series satellites.…”

    Model analysis of biases in the satellite-diagnosed aerosol effect on the cloud liquid water path by H. Kokkola, H. Kokkola, J. Tonttila, S. M. Calderón, S. Romakkaniemi, A. Lipponen, A. Peräkorpi, T. Mielonen, E. Gryspeerdt, T. H. Virtanen, P. Kolmonen, A. Arola

    Published 2025-02-01
    “…We compare this correlation directly from the model to the correlation derived using equations which are used to retrieve liquid water path from satellite observations. Our comparison shows that spatial variability in cloud properties and instrumental noise in satellite retrievals of cloud optical depth and cloud effective radii results in bias in the satellite-derived liquid water path. …”
