Selective Range Iterative Adaptive Approach for High-Resolution DOA Estimation

IEEE Access, 2019
In this paper, the problem of direction-of-arrival (DOA) estimation for a uniform linear array with single-snapshot observations is addressed. Two non-parametric DOA estimators are developed, which can be applied in any azimuth range with one snapshot ...
