摘　　要：Watterson模型在众多短波电离层信道模型中应用较多的一种模型,从理论上分析了电离层信道Watterson模型的谱密度函数,论证了Watterson仿真模型能实现影响短波通信的电离层多径、多普勒频移和多普勒频扩三个因素;然后采用Matlab的OOP技术对其进行建模仿真,研究分析了Link11数据链中的π/4-DQPSK信号通过Watterson信道模型后的误码率。仿真结果表明,Watterson模型能很好地仿真短波电离层信道特性和应用在短波数字信号通信误码率的分析。Watterson Model is applied more than other HF ionosphere channel model,three main factors of ionosphere channel affecting performance of communication system were analyzed in theory,and were realized in simulation.Matlab-based object-oriented approach was used in modeling Watterson Model,the BER of π/4-DQPSK baseband signal of Link11 passing Watterson Model was analyzed.The result of simulation predicts that Watterson Model can simulate the characteristic of HF ionosphere channel and analyze the performance of HF communication system.
