摘要

To improve the reliability and stability of optical fiber coding target location testing system, it is necessary to research the bit error rate of system under complex atmospheric conditions. This article introduces the optical fiber coding measurement system and testing principle, utilizes their measurement geometric model to calculate the coordinate of dynamic target, atmospheric attenuation and atmospheric turbulence simultaneously present and affect the power of laser in atmospheric channel, establishes the model of signal to noise ratio of photoelectric sensor, derives new bit error rate model under complex atmospheric conditions, and analyzes relevant influencing factors. The results of calculation and experimental data indicate that atmospheric turbulence and the power of laser affect bit error rate of system, with the increment of atmospheric turbulence, the bit error rate of system increases. We can improve the power of laser to effectively reduce bit error rate of systemunder the same atmospheric condition.
