摘　　要：针对一种环形结构的鱼雷电磁引信辐射器辐射场的计算问题,将该环形辐射器等效成正交磁偶极子,给出磁矩分量的表达式,通过对各磁矩分量产生的辐射场进行分解与叠加,推导出环形辐射器辐射场的数学模型。仿真结果表明:该结构的环形辐射器辐射场具有较好的对称性与均匀性,可满足反舰和反潜电磁引信对鱼雷过靶通过特性的检测需求。In order to calculate the radiation field of a annular torpedo electromagnetic fuze radiator,the annular radiator is equivalent to an orthogonal magnetic dipole,and the expression of the magnetic momen t components is given.Through the decomposition and superposition of the radiation field produced by each magnetic moment component,the mathematical model of the annular radiator radiation field is derived.The simulation results show that the radiation field of the annular radiator has good symmetry and uniformity,which can meet the detection requirements of anti-ship and anti-submarine electromagnetic fuze for torpedo passing through the target.
