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1.5°内,满足飞行器控制的要求。
A new approach for gesture angles estimation based on single vector sensor is presented. The single vector sensor mounted on aircraft receives polarized electromagnetic signal from base station. MUSIC algorithm is introduced to estimate DOA and polarization parameter of the signal. Then the transformation matrix（Aircraft At- titude Matrix） from body coordinate to geographic coordinate is calculated with this estimation and the gesture angles are estimated. Matlab stimulation results verity the efficiency of the method. The error is within 1.2 de- gree and satisfies the aircraft control requirement.
