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.

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 ...

Robust prior-based Direction of Arrival estimation
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012 In certain Direction of Arrival (DOA) scenarios some of the sources are approximately known a priori. It is then desirable to be able to exploit this prior knowledge when estimating the DOAs of the unknown sources. In this paper we modify an estimator utilizing exact angular prior knowledge of some sources such that the estimator is able to exploit ...
