Abstract: Disclosed is a novel integrated sensing and communication channel modeling method combining forward scattering and backward scattering. The method includes the following steps: setting application scenarios and antenna parameters; estimating channel state information through a mono-static sensing means, and determining positions of a communication terminal and positions and motion information of scatterers that are backward scattered in environment; dividing non-line-of-sight paths of the communication channel into forward scattering paths and backward scattering paths based on whether the scatterers can be sensed by a sensing channel, generating forward scattering paths by adopting a geometric random modeling method and generating the backward scattering paths by adopting a geometric modeling method based on obtained sensing information parameters; weighted-summing the line-of-sight, the forward scattering paths, and the backward scattering paths according to probabilities to obtain a complete communication channel impulse response. The present disclosure proposes a relatively comprehensive integrated sensing and communication channel modeling method for the first time, and the simulation results of the channel model are in good agreement with measurement data and have high accuracy.
