Frequency Analysis of Acoustic Data Using Multiple-Measurement Sparse Bayesian Learning
Sensors, 2021 Passive sonar systems are used to detect the acoustic signals that are radiated from marine objects (e.g., surface ships, submarines, etc.), and an accurate estimation of the frequency components is crucial to the target detection.

Tonal signal detection in passive sonar systems using atomic norm minimization [PDF]
EURASIP Journal on Advances in Signal Processing, 2019 Abstract Frequency estimation of a tonal signal in passive sonar systems is crucial to the identification of the marine object. In the conventional techniques, a basis mismatch error caused by the discretization of the frequency domain is unavoidable, resulting in a severe degradation of the object detection quality. To overcome the basis
