The result shows that the solar radiation pressure moments play a mainly part. based on kalman filtering, three kinds of attitude determination algorithms were studied using the attitude sensor now available on the explorer : the first based on digital solar sensor ( dss ) and gyroscope when the star sensor is not available ; another based on dss, high - gain antenna ( hga ) and gyroscope when the explorer is in the earth - safe mode ; the third based on star sensor combined with gyroscope when the explorer is in the normal mode
針對配置了典型測量敏感器的深空探測器,基於擴展kalman濾波給出了其姿態確定的方法:針對星敏感器不可用情形,給出了使用太陽敏感器和速率陀螺定姿的濾波器演算法;針對安全模式下的對地穩定定向情形,給出了太陽敏感器和高增益天線融合速率陀螺信息的定姿演算法;針對正常巡航模式給出星敏感器和速率陀螺聯合定姿演算法。Because these methods do not need not only the doa of the signal ' s and the array manifold but also signal waveform, the blind beamforming algorithms using cyclostationarity signal ' s properties are the genuine blind algorithms
該方法既不需要知道來波方向和陣列流形,也不需要提供訓練數據,僅利用信號的循環平穩特性就可以實現真正意義上的盲自適應波束形成。
