摘要/Abstract

摘要： 以电磁波三维空间结构向量为参照的飞行器姿态/航向测量研究，可弥补空间参照物缺乏，丰富空间飞行器姿态/航向测量工具。本文根据各缺损电磁矢量传感器姿态位置与接收信号之间的变化规律，建立飞行器载电磁矢量传感器阵列导向矢量。根据协同导航的多个信号空间谱和最大化，实现平台姿态/航向测量。飞行器多位置的多个传感器共同测量姿态可避免遮挡，获得更高姿态精度的同时拓展了系统的适用领域。接收电磁信息完备状态下，不需导航信号，测绘平稳的杂波就能作为姿态基准。仿真试验验证了姿态估计的有效性。

Abstract: The research of spacecraft attitude measurement based on three-dimensional spatial structure vectors of electromagnetic wave can make up for the lack of space reference and enrich the attitude measurement tools of space vehicles. Based on the variational pattern between sense attitude and positions of defect electromagnetic vector sensors, the signal steering vector of polarizing array borne on a spacecraft is set up. The platform attitude measurement is realized according to the maximization of multiple signal spatial sum-spectrums of cooperative navigation. The multi-position sensors measurement can avoid occlusion, achieve higher attitude accuracy, and expand the application field of the system. In the state of receiving the full electromagnetic information, the stationary clutter can be used as the attitude reference without the navigation signal. The simulation results verify the effectiveness of the attitude estimation.

Key words: electromagnetic vector sensor, state of polarization, steering vector, attitude/heading, spatial spectrum
