摘　　要：针对由四个棒形辐射器组合成的鱼雷电磁引信辐射装置合成场的计算问题,论文从磁偶极子场的数学模型出发,将单个棒形辐射器等效成磁偶极子,给出了磁矩分量的表达式,通过对各磁矩分量产生的辐射场进行分解与叠加,最终推导出了鱼雷电磁引信辐射装置合成场的数学模型。仿真结果表明,当α30°时,对称配置的辐射装置可以等效为磁矩方向与鱼雷纵轴重合的磁偶极子模型。For calculating the compound field of torpedo electromagnetic fuze radiation device consisting of four rod radiator, this paper starts from the mathematical model of magnetic dipole field, the component expressions of magnetic moment are given by making the single rod radiator be equivalent to a magnetic dipole. Through decomposition and superimposition of radiation field generated by the respective mag netic moment components, the mathematical model of compound field of torpedo electromagnetic fuze radiation device is derived. The simula- tion results indicate that the radiation device in symmetric configuration mode can be equivalent to the magnetic dipole that magnetic moment direction coincides with torpedo longitudinal axis on condition that a is less than or equal to 30°.
