摘要：

The generalized pulse-spectrum technique (GPST), an efficient and versatile iterative inversion algorithm, is used with adaptive grids to solve both exterior (scattering) and interior (cavity) boundary-shape inverse problems of two-dimensional Helmholtz equation. Numerical simulations of nontrivial examples are carried out to test the feasibility and to study the general characteristics of GPST without the real measurement data. It is found that GPST does efficiently produce very good results.
