摘　　要：针对海上复杂的电磁环境造成电磁波传播耗损的情况,提出基于标准传播模型(Standard Propagation Model,SPM)的改进电磁波传播衰落模型。上述算法依据开阔地SPM模型,在5km传输距离内加入反射耗损模型;并根据海上降雨量的影响,加入雨衰的预测模型;根据大气对电磁波吸收的影响,加入大气吸收损耗模型。通过对标准SPM模型和改进SPM模型的仿真并与琼州海峡海面连续波(Continuous Wave,CW)测试数据对比,证明改进后的SPM模型与实测数据更加符合,能够较为准确的反映琼州海峡海面通信信道传输耗损,且提出的改进模型可作为通用模型预测海面通信耗损。In view of the electromagnetic wave propagation loss caused by complicated electromagnetic environment at sea,an improved electromagnetic wave propagation loss model based on Standard Propagation Model(SPM)is proposed.The algorithm was based on open terrain SPM model,the reflection loss model was added within 5 km transmission distance.According to the influence of the rainfall on the sea,a rain attenuation modelwas added.According to the influence of the atmosphere on the electromagnetic wave absorption,the atmospheric absorption loss model was added.The simulation results of standard SPM model and SPM model show that the improved SPM model is more consistent with the measured data and can reflect the transmission loss of the South China Sea surface communication channel more accurately.Simultaneously,the improved model can be used as a general model to predict the transmission loss on the sea.
