abstract = {<p style="text-align: justify;">This paper is devoted to numerical simulation of time domain inverse acoustic
scattering problems with a point-like scatterer, multiple point-like scatterers or normal
size scatterers. Using Green’s functions and time convolution, we propose direct sampling methods to reconstruct the location of the scatterer. The methods involve only
integral calculus without solving any equations and are easy to implement. Numerical
experiments show the effectiveness and robustness of the methods.</p>},
