摘要
根据激光对潜通信系统的信道特性和探测器特性，推导并简化了输出信噪比公式．在探测器产生光电子的概率为泊松分布和高斯分布的情况下，分别对信号的探测率和虚警率进行了定量的计算．并综合考虑了各种因素的影响。
Based on the channel and detector characteristics of a submarine laser communication system, the output equation for the signal to noise ratio is derived and simplified. When the probability of the photoelectrons produced by the detector is of Poisson or Gaussian distribution, the detectivity and false alarm probability of the signal are calculated respectively. By taking into account all the influences of various factors, the relations between the maximum communication depth and single pulse energy are listed and the Z K d curves are plotted according to the results of calculation.
