利用零相位Kaiser窗滤波器改善MEX多普勒数据定轨精度
|
Abstract:
精密轨道确定在深空探测中至关重要，而定轨数据中的白噪声会影响定轨性能。基于零相位分析，比较了FRR （forward-filter reverse-filter reverse-output）、RRF （reverse-filter reverse-filter forward-output）和Matlab中的filtfilt这3种滤波器的优劣，设计了一种零相位Kaiser窗低通滤波器。利用火星快车号（Mars Express，MEX）的仿真数据和实测数据验证了零相位Kaiser窗低通滤波器的性能，结果发现滤除白噪声后MEX数据的定轨精度有了显著改善。双程测速数据残差均方根（root mean square，RMS）减小为原来的1/3左右，达到了0.031 mm/s；轨道位置和速度与欧空局（European Space Agency，ESA）精密轨道的差异明显变小。该滤波算法作为定轨前的数据预处理可以提高定轨精度，从而为中国火星探测器的轨道数据处理提供一定的参考
