Abstract :
We introduce the logic process of the TRM derivation, and propose the assumptions for the implementation of the TRM. The numerical simulations are conducted with four sound sources models including one point source, two adjacent point sources, sources on a circle and sources on two closed curves, to evaluate the performance of TRM and its application to MAT. The results show that the TRM can precisely reconstruct the MAT sound source from the detected acoustic pressure.
