根据电磁理论和光栅方程给出线源天线轴线能量的解析公式,得到波的矢量积分的最大值与阵元数目的平方成正比。并在不同实验条件下测试天线阵列在轴线方向的电场强度和能量密度,在实验误差范围内可以得出:电场强度与天线单元数成正比,能量密度与天线单元数的平方成正比。这说明瞬态阵列电磁脉冲可以很好地实现同相合成。
According to the electromagnetic theory and the grating equation, the analytical formula of the axial energy of the source antenna is given. The maximum value of the vector integral of the wave is proportional to the square of the number of elements. And in different experimental conditions test the antenna array in the axial direction of the electric field strength and energy density can be drawn within the experimental error range: electric field strength and the number of antenna elements is proportional to the energy density is proportional to the square of the number of antenna elements. This shows that the transient array of electromagnetic pulses can be well in-phase synthesis.
