摘要 提出了一种基于散射模型的等价相对边界条件。将该等价相对边界条件与传统FDTD方法相结合提出了求解运动导体目标电磁散射问题的方法。并将该方法用于计算运动的无限大导体表面的电磁散射问题,计算结果与文献所给方法的计算结果吻合很好,验证了该方法求解运动导体目标电磁散射问题的正确性和有效性。用该方法计算了运动三维导体目标的雷达散射截面。 A kind of equivalent form of relativistic boundary conditions based on scattering model is proposed. A method which can solve the electromagnetic scattering problem of moving perfectly conducting objects is proposed with the equivalent form of relativistic boundary conditions combining the conventional FDTD. This method has been used to calculate the scattering from the infinite perfectly conducting surface moving in high speed and the result of this method is in good agreement with the result of the method in literature, the correctness and efficiency of this method for electromagnetic scattering from moving conducting objects is verified. The radar cross section（RCS）of three dimensions conducting objects moving in high speed is calculated.
