论文摘要
我们提出了一种在这种情况下具有时间依赖性的部分连贯源和时间依赖的随机异质介质的理论。我们的目标是了解测量强度的闪烁指数如何取决于源和中等参数。我们从对随机波方程的渐近分析中推断出闪烁指数的一般形式，并以各种缩放制度评估了这一点。闪烁指数是一种基本数量，用于分析和优化成像和通信方案。我们的结果对于量化现实传播方案下的闪烁指数很有用并解决此类优化挑战。
We present a theory for wave scintillation in the situation with a time-dependent partially coherent source and a time-dependent randomly heterogeneous medium. Our objective is to understand how the scintillation index of the measured intensity depends on the source and medium parameters. We deduce from an asymptotic analysis of the random wave equation a general form of the scintillation index and we evaluate this in various scaling regimes. The scintillation index is a fundamental quantity that is used to analyze and optimize imaging and communication schemes. Our results are useful to quantify the scintillation index under realistic propagation scenarios and to address such optimization challenges.
