The average received intensity and the intensity fluctuations in weakly turbulent media are derived for finite-sized sources of arbitrary degree of coherence (both spatial and temporal). Spatial partial coherence is modelled by random shifts and tilts of the source phase. With this simple model of source coherence, we are able to obtain the correct average intensity when the source is coherent, partially coherent and incoherent. The scintillation index as measured by a slow detector is formulated by introducing the temporal as well as spatial effects in the source coherence. Transmitter and frequency averaging effects are shown as special cases of our results.
