Adaptive Frequency-Domain Sparsity Control Based on Kullback–Leibler Divergence for Tonal Enhancement in Passive Sonar
Tonal components embedded in the radiated noise of underwater targets constitute critical spectral features in passive acoustic measurement systems. To improve the reliability of tonal measurement under colored noise and low-signal-to-noise-ratio (SNR) conditions, this article proposes a robust Kullback–Leibler diverge...
