Enhanced CACIS configuration for direction of arrival estimation
Electronics Letters, 2022 In this letter, an enhanced coprime array with compressed inter‐element spacing is designed for direction of arrival estimation. First, we analyse and conclude that the 0th sensor of coprime array with compressed inter‐element spacing is redundant for ...

Radar Antenna Selection for Direction-of-Arrival Estimations [PDF]
2021 IEEE Radar Conference (RadarConf21), 2021 Multi-antenna radars exhibit positively correlated detection performance with the number of elements utilized. The feasibility of refining antenna arrays to reduce cost of operation with only marginal loss of performance has attracted significant attention as utilizing a large number of elements may be prohibitively costly in terms of computation and ...

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.

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 ...

Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids [PDF]
, 2015 Sound sources at the same angle in front or behind a two-microphone array (e.g., bilateral hearing aids) produce the same time delay and two estimates for the direction of arrival: A front-back confusion.
