Research on Underdetermined DOA Estimation Method with Unknown Number of Sources Based on Improved CNN

This paper proposes a joint estimation method for source number and DOA based on an improved convolutional neural network for unknown source number and undetermined DOA estimation. By analyzing the signal model, the paper designs a convolutional neural network model based on the existence of a mappi...
