To reduce the bit error rate of data transmission in the field of the long-distance ballistic trajectory of weapon range, this article utilizes a MIMO-OFDM atmospheric laser link communication model to transfer the obtained data using the four-screen measurement system in the terminal ballistic. First, the atmospheric attenuation channel model caused by haze and fog in the atmospheric link communication is analyzed. Then the atmospheric attenuation factors of haze day are introduced and the received optical power of the system is calculated. Lastly, the atmospheric laser link communication model in different weather environment is established. The calculation functions of signal-to-noise ratio and bit error rate in the long-distance link communication are derived. Through the calculation and analysis, the attenuation of laser's power caused by fog and haze with different visibilities is obtained. The results show that the lower is the visibility under fog or haze days, the faster is the attenuation of the laser's power and the higher is the bit error rate of the communication link. The atmospheric attenuation can be reduced by increasing the laser's power. The results verify the feasibility of the MIMO-OFDM atmospheric laser link communication model. The proposed model has a certain guiding significance for the further study of reliable data transmission in the ultra-long-range ballistic.
