Abstract

In a weakly marine turbulent medium, formulation of the on-axis scintillation index of a flat topped Gaussian beam is derived by using the Rytov method and the intensity has log-normal distribution expressed. The scintillation index and average bit error rate < BER > with respect to changes in propagation distance, wavelength, beam size, and average signal to noise ratio < SNR > are exhibited. Our results indicated that small < BER > advantage can be achieved in weak atmospheric marine when focal length equals to propagation distance and when the order of flatness is small value.
