Abstract

By using a complex phase screen model for a diffuser located at the transmitter, analytic expressions are developed for the scintillation index of a lowest order Gaussian-beam wave in the pupil plane of the receiver in weak and strong atmospheric conditions. The effect of partial coherence on the scintillation index is analyzed as a function of the propagation distance and the correlation length of the diffuser. The reduction in the scintillation level (due to the transmitter aperture averaging effect) is shown under all atmospheric conditions. The signal to noise ratio and the bit error rates (for OOK signal modulation) are discussed.
