Two New Techniques for Direction of Arrival Estimation

Direction of Arrival estimation (DoA) is one of the most demanding problems which one has to solve for localizing and tracking multiple rapidly moving targets as in radar, mobile communication and in other areas. In this paper, two new techniques for DoA estimation of signals impinging on the array are proposed. First, the usage of an electronically rotation of the plane of the linear array by small ang le in one dimension DoA estimation is presented. Second, a modified Matrix Pencil (MP) technique for two dimensional DoA estimation is presented. The analysis of the two algorithms is discussed. The accuracy of the DoA estimation of the two proposed techniques is observed through simulated numerical examples.
