time reversal, space-frequency decomposition, ESPRIT algorithmAbstract
A novel time reversal approach for the point target imaging is proposed in this paper. This method requires only single measurement by the time reversal array, and employs the space-frequency decomposition plus the rotation invariance of the signal subspace for the target detecting. Numerical simulations are carried out to validate the performance of the proposed method for single target located at different positions in homogenous and continuous random medium respectively. The results indicate that the proposed method performs better than the conventional signal subspace based space-frequency algorithm both in imaging resolution and efficiency.
