提出了一种有效的球面等效面区域分解方法，用于旋转运动体从近耦合区到远耦合区的电磁建模和成像。用一系列相对于时间的静止矩对运动物体进行建模，每个物体被一个球面等效面包围。在近耦合区，用球面等效面之间的耦合来评价多个BoRs之间的耦合。在远耦合区，将各球面等效面散射场叠加得到总散射场。对于静止时刻不同相对位置的运动物体，等效过程仅用联合场积分方程（CFIE）和Poggio-Miller-Chang-Harrington-Wu-Tsai （PMCHWT）分别进行一次计算。利用所提出的区域分解方法对散射电磁场进行评估，得到雷达图像。大大提高了计算精度和效率。数值结果和讨论证明了该方法对导电和介电混合多运动物体的建模和成像的有效性。
We propose an effective domain decomposition method with a spherical equivalence surface for the electromagnetic modeling and imaging of moving bodies of revolution (BoRs) from near coupling to far coupling region. The moving BoRs are modeled with a series of stationary moments with respect to the time, each object is enclosed by a spherical equivalence surface. In the near coupling region, the couplings between multiple BoRs are evaluated with the couplings between spherical equivalence surfaces. While in the far coupling region, the total scattering fields are obtained by the superposition of the scattering fields from each spherical equivalence surface. For the moving objects with different relative positions at stationary moments, the equivalence processes are evaluated only once with combined field integral equation (CFIE) and Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) equations for conductive and dielectric objects, respectively. The radar images are obtained from the scattering electromagnetic fields evaluated by the proposed domain decomposition method. Both computation accuracy and efficiency are enhanced significantly. Numerical results and discussions demonstrate the validity of the proposed method for modeling and imaging of mixed conductive and dielectric multiple moving objects.
