Direction-of-Arrival Estimation Methods in Interferometric Echo Sounding [PDF]
Sensors, 2020 Nowadays, there are two leading sea sounding technologies: the multibeam echo sounder and the multiphase echo sounder (also known as phase-difference side scan sonar or bathymetric side scan sonar). Both solutions have their advantages and disadvantages,

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.

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.

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

Small Aperture Antenna Arrays for Direction of Arrival Estimation [PDF]
SensorsIn this paper, we establish criteria for the design of small aperture antenna arrays for Direction of Arrival (DOA) estimation. We define a small aperture antenna array as one consisting of a few elements with an average interelement spacing less than or
