摘要
为了基于接收极化电磁波的三维极化分量对其到达方向进行估计,讨论了通过极化参数来描述极化电磁波及通过已知复合电场求取极化参数的问题,提出利用矢量对几何位形进行描述,通过三维振子天线测量复合电场的电波矢量,从而利用电波矢量的3个分量求取发射电磁波的到达方向(DOA)的一种新算法,基于此算法,利用仿真的极化电磁波进行了DOA估计仿真实验,并与传统的空间谱估计算法进行对比,对比发现,提出的DOA估计算法是更为有效的。
To estimating the direction of arrival of a received electronic magnetic wave based on its three dimensional polarization components, in this paper the issue of utilizing polarization parameters to describe the electromagnetic wave and using the known compound electric field to composite its polarization parameters is investigated. An new approach based on vector analysis method is adopted that can closely combine geometric configuration and algebraic operation in the process of polarized electromagnetic wave transmitting and receiving. Basing on this approach, simu- lation experiments are carried out with simulated electronic magnetic wave. The simulation results of this approach are compared with the results of the traditional spatial spectrum estimation algorithm. It is found that the DOA estimation approach proposed by this paper is more effective.
