流星余迹信道建模与仿真分析

为检验流星余迹通信设备及软件在实战化环境中的应用效能，针对流星余迹通信信道规律复杂、实测代价高等问题，建立流星余迹信道仿真模型。通过对典型数学模型的深入研究，以欠密类流星余迹和过密类流星余迹信道模型为基础，融入了欠密类流星簇和多径信道两种特殊类型，按照概率论原理，建立了流星余迹信道混合模型，并结合流星余迹到达间隔模型，利用C++实现了流星余迹信道混合模型的仿真。该模型可生成包含单颗欠密类、单颗过密类、欠密类流星簇和多径信道等多种类型的复杂信道。仿真结果表明，所产生的流星余迹信道特征与实际信道基本相符，验证了该模型的可用性和合理性。

Modeling and simulation of meteor burst channel

In the test of the actual performance of communication device and software based on meteor burst,a model of meteor burst communication channel was established to solve the complexity of channel and difficulty of measurement.By analyzing the mathematic models of meteor burst channel,single underdense meteor trail channel and single overdense meteor trial channel were modeled as basis.Underdense meteor cluster and multipath channel were proposed to built a hybrid model based on probability principles.Combining with meteor arrival interval model,the simulation of meteor burst channel was realized by C++ programming tool.The simulation result can provide underdense meteor trail,overdense meteor trial,underdense meteor cluster and multipath channel.It indicates that the characteristics of the meteor burst channel model are basically matched with those of real channel.The result verifies usability and justifiability of the model.
