Article Synopsis
- Small- and medium-scale scattering can significantly distort acoustic imaging due to frequency-dependent phase changes, making it difficult to interpret signals in multi-channel recordings.
- The proposed compensation methods involve two steps: creating a rough signal guide using extensive beamforming, and applying specialized time-frequency masking for each trace to restore the corrupted phase and amplitude information.
- The use of phase masks helps enhance the clarity of target events, while amplitude masks effectively eliminate unwanted background noise, ensuring clear signals without losing frequency resolution.
