| 摘 要： | 提出使用单矢量传感器进行飞行器姿态角估计的新方法，安装在飞行器平台的单电磁
矢量传感器接收来自基站的极化电磁波信号，用MUSIC算法进行信号DOA和极化参数估计，得
到机体坐标系到地理坐标系的转换矩阵即飞行器姿态矩阵，最终估计飞行器姿态角。Matlab
仿真验证了该方法的有效性，姿态角估计误差在15°内，满足飞行器控制的要求。

| Abstract: | A new approach for gesture angles estimation based on single vector senso
r is presented.The single vector sensor mounted on aircraft receives polariz
ed electromagnetic signal from ba
se station. MUSIC algorithm is introduced to
estimate DOA and polarization parameter of the signal. Then the transformation m
atrix(Aircraft Attitude Matrix) from body coordinate to geographic coordin
ate is calculated with this estimation and the gesture angles are estimated. Mat
l
ab stimulation results verity the efficiency of the method. The error is within
1.2 degree and satisfies the a
ircraft control requirement. |
