Abstract

A practical technique is presented for finding the shape of smooth, reflecting objects from their scattered fields. The method assumes the field on the surface of the objects satisfy Dirichlet or Neumann boundary conditions. A surface identifier combines eigenfunctions satisfying the boundary conditions for the particular object shape. The eigenfunctions are found from the T matrix. The T matrix is found from a near field recording by a holographic imaging technique which truncates the estimated T matrix guaranteeing a stable inversion. Many successive illuminations of the object are required to determine the T matrix completely.
