Remote Sensing Image Reconstruction under Challenging Observations
Research on remote sensing image reconstruction, enhancement, and 3D perception from noisy and incomplete observations.
- Remote Sensing Reconstruction: Developed physics-aware and learning-based methods for high-resolution radar imaging under low-SNR, sparse-sampling, and complex-motion conditions.
- Time-Frequency Analysis & Estimation: Modelled non-stationary radar time series and developed nonlinear parameter-estimation methods for weak-target detection under low-SNR conditions.
- Image Enhancement: Developed self-supervised approaches for image denoising and structure-preserving enhancement.
