摘要: 在当今的物联网社会,位置信息是实现万物相连的基础技术之一。作为一种高精度的定位信号,超宽带信号具有高时间分辨率、穿透性强等特点,适用于各种环境下的人员、物资、车辆定位,具有非常广阔的应用前景。文中提出了一种基于阵列接收天线的到达角估计方法,在获得接收天线阵元间传输线路的延迟时间后,对接收机内部确定的计时时间信号进行解算,可以估计出接收阵列天线虚拟中心阵元与发射天线之间360度范围内的到达角度,弥补了传统AOA方法中只能估计180°范围内到达角的缺陷。MATLAB仿真结果表明:此方法可以有效地估计出360°范围内虚拟中心阵元的到达角度,具有一定的可行性与实用性。

关键词: AOA定位, 超宽带信号, 阵列天线

Abstract: In today’s Internet of Things society,location information is one of the basic technologies that connect everything.As a high-precision positioning signal,the ultra-wideband signal has the characteristics of high time resolution,strong penetrability,etc.,and is suitable for the positioning of people,materials,and vehicles in various environments,which has a broad application prospect.This paper proposed an angle-of-arrival estimation method based on an array receiving antenna,after obtaining the delay time of the transmission line between the receiving antenna elements.The timing time signal determined within the receiver is solved to estimate the angle of arrival ofthe virtual center element of the receiving array antenna.This method can estimate the angle of arrival within a 360-degree range between the array element and the transmitting antenna,overcomes the defect can the conventional AOA method can only estimate the angle of arrival within a range of 180 degrees.The results of MATLAB simulation show that this method can effectively estimate the arrival angle of the virtual center array element within 360 degrees,which has certain feasibility and practicality.

Key words: AOA positioning, Array antenna, Ultra-wideband signal
