The interference of noise used to depredate the performance of the conventional time-domain back-projection (BP) imaging method. In this letter, a projection imaging method is proposed for noise suppression. The proposed method utilizes the symmetry of the cross-correlation function of the ideal echo signal and the realistic one to suppress the interference of noise. The performance of the proposed...
In this paper, a novel time reversal imaging (TRI) algorithm for damage detection in concrete is presented. The standard time reversal imaging method typically suffers from performance degradation when the echo signals are interfered by strong noise. The proposed method is developed to address the aforementioned issues. First, the echo signals are time reversed and rebroadcasted from each receiver's...
