The shape of an EM pulse wave propagating through dispersive-strong turbulence shows asymmetry, with an exponentially decaying tail due to different pulse components traversing different paths. An accurate expression for the pulse shape is identified in literature, but is intricate and seldom used. Instead, the model of a Gaussian convolved with an exponential is assumed more often. Here, a relatively simple expression is derived for the average intensity of a narrowband Gaussian pulse propagating through dispersive-strong turbulence, which reduces to familiar results in the absence of dispersion. Comparisons to well known pulse models is carried out. Furthermore, the validity of the proposed model is tested for the application of radiations from pulsars.

通过色散强湍流传播的 EM 脉冲波的形状显示出不对称性，由于不同的脉冲分量穿过不同的路径，其尾部呈指数衰减。文献中确定了脉冲形状的准确表达，但很复杂且很少使用。取而代之的是，更多地假设了与指数卷积的高斯模型。在这里，推导出了通过色散强湍流传播的窄带高斯脉冲的平均强度的一个相对简单的表达式，在没有色散的情况下，它可以简化为熟悉的结果。与众所周知的脉冲模型进行比较。此外，对所提出模型的有效性进行了测试，以用于脉冲星辐射的应用。
