Shortwave broadband mobile channel model is the basis for performance analysis and evaluation of mobile communication systems on remote mobile platforms. The existing shortwave broadband channel model cannot effectively characterize the fast time-varying Doppler effect of the mobile channel of the mobile platform, which is difficult to adapt to the shortwave mobile communication needs of the mobile platform. Therefore, an expression for the mobile channel impulse response of the maneuvering platform were derived based on the analysis of the mapping relationship between the behavior pattern of the maneuvering platform and the time-varying Doppler effect of the channel. And a shortwave communication channel model was also proposed based on the ITS (international telecommunication society) model for different scenarios of fixed and mobile, different propagation modes, and broadband and narrowband convergence. The validity of the channel model was verified in two dimensions: time domain dispersion and frequency domain dispersion using channel impulse response and channel scattering function. The results show that the channel model can achieve time-varying Doppler effect propagation reproduction and channel simulation based on the motion trajectory of the maneuvering platform. It is also possible to realize the maneuvering platform shortwave broadband channel simulation with each state ephemeris based on a priori information such as vehicle type and maneuvering frequency when the motion trajectory is unknown, which is important for the maneuvering platform shortwave mobile communication system effectiveness evaluation.
