Enhanced and Generalized Coprime Array for Direction of Arrival Estimation
IEEE Transactions on Aerospace and Electronic Systems, 2023Owing to the large degrees of freedom and reduced mutual coupling by generating difference coarrays, nonuniform linear arrays have aroused great interest in direction of arrival estimation. Previous works have shown some improved sparse arrays, while few

High Resolution Estimation of Directions of Arrival
2005 IEEE 61st Vehicular Technology Conference, 2005In this paper, we propose a novel system architecture that employs the flexible tree search based orthogonal matching pursuit (FTB-OMP) algorithm for direction of arrival estimation. It is shown by simulation results that the FTB-OMP algorithm has high estimation performance and resolution capability when compared to the MUSIC and OMP algorithms.

An Off-Grid Iterative Reweighted Approach to One-Bit Direction of Arrival Estimation
IEEE Transactions on Vehicular Technology, 2023This article addresses the problem of direction of arrival (DOA) estimation only relying on the sign bits of the array signal. A new optimization model is formulated to realize the simultaneous estimation of one-bit DOAs and source number.

Target direction-of-arrival (DOA) estimation is often difficult in the presence of strong interference-especially when the target DOA is very close to the interference DOA-since the strong interference signal can mask the weak target signal and make the ...

Compressive wideband direction of arrival estimation
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015Compressive Sampling (CS) has recently emerged as a groundbreaking technique which reconstructs the sparse signal using samples taken below Nyquist sampling frequency (sub-Nyquist samples). In this paper we consider to estimate the Direction of Arrival (DOA) of wideband signals using sub-Nyquist samples.
