A Novel Direction-of-Arrival Estimation via Phase Retrieval with Unknown Sensor Gain-and-Phase Errors

Sensors, 2019
In signal array processing, high-resolution direction-of-arrival (DOA) estimation algorithms work well on the assumption that the system models are perfect. However, in practicality, there are imperfect system models in which sensor gain-and-phase errors

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 ...

General direction-of-arrival tracking with acoustic nodes [PDF]

In this paper, we propose a particle filter acoustic direction-of-arrival (DOA) tracker to track multiple maneuvering targets using a state space approach. The particle filter determines its state vector using a batch of DOA estimates.

Experimental validation of spatial spectrum suppression algorithms for interference sources

Dianzi Jishu Yingyong
In the actual direction finding system, when the weak signal and the strong interference are spatially close, the spatial spectrum direction finding system can only estimate the direction of arrival (DOA) for the strong interference, and the performance ...
