A Parameter-Based Atmospheric Phase Compensation Method for Millimeter-wave Communication Sensing Systems

In future 6G systems, communication signals can achieve high-precision sensing functions, and the sensing function helps improve communication performance. However, atmospheric changes can affect the sensing accuracy, for example, geological disaster monitoring and building deformation monitoring. Considering the limited accuracy of atmospheric correction using the refractive index model, this article proposes a method based on the refractive index model and multipath information. This method uses multipath information and meteorological data to correct the refractive index model and improve the accuracy of atmospheric compensation. Experimental results show that the proposed method can effectively eliminate atmospheric effects.
