N2 - With the traditional FDTD method, the Huygens surface is set around target and the result of near-to-far-field transformation is scattering properties of the entire target in far field. However, in high-resolution microwave remote sensing systems, local scattering characteristics of the target body are more hoped for, and the traditional calculation process can't meet this demand. In this paper, a new method is proposed which aims to calculate near-to-far-field transformation in FDTD to meet this requirement. In this method, the Huygens surface coincides with local scattering body, thereby the near-to-far-field transformation of the local surface in target is realized, and far-field scattering characteristics of each part in the objectives are obtained. Simulation results of typical target show that the method proposed in this paper could make the local-to-global scattering come true, and meet the demand of study on target scattering characteristic in high-resolution radar.
