Variational Time-frequency Mode Tracking Decomposition
A variational mode decomposition method based on time-frequency analysis
This MATLAB implementation accompanies the research paper by H. Dong, T. Shan, G. Yu, Y. Shi, and Y. Chen, 《Variational Time-Frequency Mode Tracking for Micro-Doppler Signature Extraction》, Signal Processing, 2025. VTFMTD integrates variational optimization with the short-time Fourier transform to decompose composite radar signals into intrinsic modes and accurately estimate their instantaneous frequencies. The method offers high robustness to noise and strong amplitude modulation through adaptive time-frequency Wiener filtering and iterative centroid-based IF refinement. If you use this code in your research or any publication, please cite the original paper.
The paper has been acceptted by Signal Processing.
This software is a simplified version of the algorithm and is only used for scientific research and testing analysis. If there is any commercial use, please contact us dhr19970808@163.com
