分析了星地相干激光二进制相移键控(BPSK)通信系统中自适应校正波前残差与相干效率的关系;讨论了自适应校正下相干效率和误码概率的动态特征;然后,研究了大气闪烁对相干效率和通信误码率的影响。在假设接收强度均匀分布的前提下建立了波前残差均方根值与相干效率的理论关系,采用频率直方图方法仿真了相干效率以及相应的误码概率的概率分布函数,计算了不同校正残差和闪烁条件下的通信平均误码率。结果表明:波前残差大于1rad时,相干效率主要受波前残差影响,自适应校正性能达到衍射极限时才能获得10
-8
的误码率,但此时大气闪烁可能会使误码率增大两个数量级。
The relationship between the residual wavefront error of an adaptive optical system and the coherence efficiency in a satellite to ground coherent Binary Phase Shift Keying(BPSK) laser communication system was explored.The dynamic characteristics of coherence efficiency and the Bit Error Probability(BEP) under adaptive optical correction were discussed
then the influence of atmospherical scintillation on the Bit Error Ratio(BER) of coherent laser communication was analyzed.The theoretical relationship between the Root Mean Square(RMS) of residual wavefront error and the coherence efficiency was derived under an assumption of the uniform intensity distribution.Through the histogram frequency method
the cumulative distribution function of coherence efficiency and BEP were simulated
and the mean BER of communication system was calculated.The results show that the coherence efficiency is mainly affected by the residual wavefront error when the RMS of residual wavefront error is above 1 rad.Moreover
the BER can reach 10
-8
level when the adaptive correction achieves diffraction limit.In this case
the BER from atmospherical scintillation may increase 100 times.
