Recognition of intrapulse modulation mode in radar signal with BRN-EST

Year: 2025

Type: article

Abstract: Neural network-based methods for intrapulse modulation recognition in radar signals have demonstrated significant improvements in classification accuracy. However, these approaches often rely on complex network structures, resulting in high computational resource requirements that limit their practical deployment in real-world settings. To address this issue, this paper proposes a Bottleneck Residual Network with Efficient Soft-Thresholding (BRN-EST) network, which integrates multiple lightweight design strategies and noise-reduction modules to maintain high recognition accuracy while significantly reducing computational complexity. Experimental results on the classical low-probability-of-intercept radar signal dataset demonstrate that BRN-EST achieves comparable accuracy to state-of-the-art methods while reducing computational complexity by approximately 50%.
