摘　　要：根据单元天线辐射瞬态电磁脉冲轴线能量传输特性的解析解,提出了阵列辐射瞬态电磁脉冲的点源近似模型,给出阵列辐射瞬态电磁脉冲高效合成特性的物理实质。并采用阵列瞬态电磁脉冲产生系统,对高效合成特性进行实验验证。实验结果和采用点源近似模型计算结果都很好地证明了阵列瞬态电磁脉冲的高效合成特性。On the basis of the analytical solution of axial energy propagation of transient electromagnetic pulse from an antenna unit, point source approximation model for transient electromagnetic pulses radiated from antenna array is introduced, and the physical mechanism of the effective energy density superposition is given. Arrayed transient electromagnetic pulse generator is used to prove the effective energy density superposition. Both of the experimental results and calculated results using point source approximation model confirm the effective energy density superposition of transient electromagnetic pulses from antenna array.
