要約(日本語): We analyze 3-D electromagnetic scattering problems by using the fast multipole method (FMM) and discuss the computational accuracy. The truncation of translation operators relates to one of the computational error sources of FMM. A modified approach is proposed to predict and control the computational error of radar cross sections under the desired digits of accuracy.
