A DOA Estimation Method Based on an Improved Transformer Model for Uniform Linear Arrays with Low SNR
In this paper, the Star-Transformer model is improved to obtain more accurate direction of arrivals (DOA) estimation of underwater sonar uniform linear array (ULA) under low signal-to-noise ratio (SNR) conditions. The ideal real covariance matrix is divided into three channels: real part channel, im...
