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.

Accurate Direction-of-Arrival Estimation Method based on Space-Time Modulated Metasurface
IEEE Transactions on Antennas and Propagation, 2022 A metasurface-based Direction of Arrival (DoA) estimation method is presented. The method exploits the properties of space-time modulated reflective metasurfaces to estimate in real-time the impinging angle of an illuminating monochromatic plane wave ...

Prior knowledge-based direction of arrival estimation
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011 In a number of direction of arrival (DOA) estimation applications there exists prior knowledge about the sources whose bearings are to be determined. We study the case when this prior information concerns some of the source positions and their correlation state, which is a relevant case in, for example, RADAR scenarios where stationary objects exists ...

Direction of Arrival Estimation of Sound Sources Using Icosahedral CNNs [PDF]
IEEE/ACM Transactions on Audio Speech and Language Processing, 2022 In this paper, we present a new model for Direction of Arrival (DOA) estimation of sound sources based on an Icosahedral Convolutional Neural Network (CNN) applied over SRP-PHAT power maps computed from the signals received by a microphone array.
