摘　　要：为分析电磁脉冲与短波天线的耦合特性,采用计算电磁学矩量法,提出求解天线问题的一般思路。首先采用分域基函数计算出天线的表面电流与输入阻抗,并与FEKO仿真结果相比较,验证该方法的正确性;再计算了激励为电磁脉冲时,通过天线耦合产生的感应电流的频域及时域响应,对系统的电磁脉冲损伤分析有较好的参考价值。The method of moments is adopted and a common idea to solve the problems of antenna is proposed to analyze the coupling characteristic of electromagnetic pulse and HF antenna.The surface current and input impedance of the HF antenna are calculted with the sub-domain basis functions.And the calculated results are compared with those of FEKO simulation to verify the correctness of the method.The induction urrent produced by the coupling of the high-altitude electromagnetic pulse（HEMP） and the response of scattered field in frequency domain and time domain is calculated.The conclusion has a certain reference value on the analysis of system electromagnetic pulse damage.
