摘要
详细分析了湍流介质中二阶矩方程的数值差分方法。利用不同的波结构函数模型 ,计算了平面脉冲波在湍流介质中传播的双频互相关函数的实部和虚部 ,直接应用于脉冲展宽、脉冲强度等问题的计算中。为应用于脉冲波传播特性分析 ,提供必要的理论基础和方法。同时 ,也可以推广应用到处理复宗量函数的同类偏微分方程问题中。
The detail of the numerical difference method on the second moments equation was discussed. According to the variously wave structure function, we had computed the real and image parts of the two-frequency mutual coherence function, which could directly apply to the calculation of the pulse broaden and intensity. It is useful to solve the pulse propagation in turbulent medium and to solve the same partial difference equation with a complex-function.
