Direction-of-Arrival Estimation Based on Joint Sparsity [PDF]
Sensors, 2011 We present a DOA estimation algorithm, called Joint-Sparse DOA to address the problem of Direction-of-Arrival (DOA) estimation using sensor arrays. Firstly, DOA estimation is cast as the joint-sparse recovery problem.

No‐search algorithm for direction of arrival estimation [PDF]
Radio Science, 2009 Direction of arrival estimation (DOA) is an important problem in ionospheric research and electromagnetics as well as many other fields. When superresolution techniques are used, a computationally expensive search should be performed in general. In this paper, a no‐search algorithm is presented.

Direction of Arrival Estimation Algorithm Based on Coprime Array [PDF]
Hangkong bingqi, 2023 The coprime array has attracted extensive attention because of its flexible antenna placement form and larger array aperture compared with the uniform array, which can obtain higher degrees of freedom and reduce the cost of hardware resources.

On the Error Metrics Used for Direction of Arrival Estimation. [PDF]
Sensors (Basel)In this article, the error metrics used for evaluating the performance of direction of arrival (DoA) estimation are thoroughly investigated to recommend the most suitable one. This investigation highlights the lack of consensus in the literature regarding the selection and definition of these metrics. We show that this disparity is particularly serious

Amplitude Only Direction of Arrival Estimation
2023 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2023 In this manuscript, we present a novel hardware concept for the estimation of the direction of arrival of electro-magnetic signals. An arrangement of two patch antenna arrays, tilted with respect to each other, is used to create a monotonic relationship between the DoA and the received power difference between both arrays.
