弱大气湍流的闪烁指数是针对部分相干源（在空间和时间上）制定的。我们获得了探测器响应时间较慢和较快的两种情况的结果。我们的解决方案在相干和非相干源的限制下正确地减少到已知的闪烁指数。发射机孔径平均和频率平均效应显示为我们结果的特殊情况。讨论了所使用的源模型的局限性以及快速检测器获得的解决方案。
The scintillation index for weak atmospheric turbulence is formulated for a partially coherent source (in space and time). We obtain results for two cases when the detector has a slow and a fast response time. Our solutions correctly reduce to the known scintillation index in the limit of coherent and incoherent sources. Transmitter aperture averaging and frequency averaging effects are shown as special cases of our results. The limitations of the source model used and the solution obtained for a fast detector are discussed.
