Multisource DOA Estimation in Impulsive Noise Environments Using Convolutional Neural Networks

International Journal of Antennas and Propagation, 2022
This work proposes an effective high-resolution multisource direction-of-arrival (DOA) estimation method in impulsive noise scenarios based on convolutional neural networks (CNNs). First of all, the array observation matrix is preprocessed and fed into a

A Priori-Based Subarray Selection Algorithm for DOA Estimation

Sensors, 2020
A finer direction-of-arrival (DOA) estimation result needs a large and dense array; it may, however, encounter the mutual coupling effect, which degrades the performance of DOA estimation.
