摘    要:
利用光学导航相机以及星敏感器,通过测量星光信息以及天体边缘的信息,进行了自主光学导航方案的设计.利用小波分析对观测信息进行预处理,滤除了它所包含的高频噪声,为UKF(Unscented Kalman Filter)滤波过程提了更为平稳的观测信息,并与UKF滤波进行比较,通过仿真验证了该算法的优越性.

关 键 词:自主光学导航  小波分析  星敏感器  光学导航相机

Abstract:
An autonomous optical navigation scheme was designed using the star light data and body edge data which is measured by star sensor and optical navigation camera.The observation information was pretreated by wavelet analysis and the high frequency noise was filtered thus it offered the furthermore smooth observation information for the UKF(Unscented Kalman Filter).The advantage of the algorithm is showed by the simulation through compared with the UKF.
Keywords:UKF  Mallet
