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
