【摘要】 提出了一种用于时域有限差分（ＦＤＴＤ）方法的复杂目标建模过程．通过建立目标参数描述文件，进行网格剖分，最后给出ＦＤＴＤ离散模型．目标建模与ＦＤＴＤ程序结合可以计算复杂目标的ＲＣＳ．离散模型显示的数据文件具有占用内存小的特点，适合于微机运行．同时应用ＡｕｔｏＣＡＤ系统显示目标模型，对建模过程进行实时显示，以验证建模的正确性．更多还原

【Abstract】 A process modeling the complex object for the FDTD computation is presented. Making up the descriptive file for the complex object and discretizing the object, we can obtain the discretized model. In the process we apply Auto CAD to display the model. The proposed method is particularly useful for a microcomputer because it saves computer storage.更多还原
