Abstract: We proposed a new numerical algorithm for scattering problem of multiple obstacles. The algorithm used the linear combination of single layer potential function and double layer potential function to approximate the scattering field, without need to truncate and partition the domain, and the application process was simple and the convergence rate was fast. Numerical examples show the algorithm is effective.
