    摘要
  • 摘要: 为研究部分相干光通过强湍流对系统误码率的影响，借助对激光在大气湍流场中的传输方程进行解析求解（忽略系统中其他噪声，仅考虑由大气湍流引起的系统误码率），得到不同湍流内尺度、传输激光波长和光源相干参数条件下，系统误码率和传输距离的关系。结果表明：在强湍流条件下，当发射天线数目达到一定时，随着传输距离的增加，系统误码率逐渐增大，但增大到一定程度后趋于饱和；光源相干参数越大，系统误码率越低；湍流内尺度越大，系统误码率越高；传输激光波长的变化对系统误码率无明显影响。
    Abstract: A theoretical base for using the technology of multibeam transmission and the reception in the ship laser communication systems was provided by the research on the influence of partially coherent beams passing through the strong turbulence on the bit error rate. The relation between system bit error rate and transmission range was obtained under the conditions of different turbulence measurement, transmission laser wavelength and light source coherence parameter by the aid of a method to parse the equation of laser transmission in atmospheric turbulence field, ignoring other noises in the system, but considering the bit error rate caused by atmospheric turbulence only. The result indicates that under the strong turbulence condition, the system bit error rate is increased gradually with the increase of the transmission range when the quantity of transmitting antennas reaches a certain number, but the system bit error rate tends to saturation when the transmission range accretion reaches a definite degree; the bigger the light source coherence parameter increases, the lower the system bit error rate becomes; the more the turbulence inner scale is, the higher the system bit error rate becomes; and the variation of the transmission laser wavelength has no obvious influence on the system bit error rate.
