To address the inadequacy of traditional path loss models in accurately describing and characterizing sensing channels,the research on sub-terahertz path loss measurement and modeling for 6G integrated sensing and communica-tion was conducted.A sensing channel path loss model incorporating the echo characteristics of indoor materials was in-troduced based on radar cross-section theory and an angle-distance joint path loss model for sensing channels was con-structed.Using a sub-terahertz channel measurement plat-form based on a vector network analyzer,the fading character-istics of sensing channels at different angles and distances were examined.The measurement results indicate that the angle-distance joint path loss model can accurately capture the variation patterns of sensing channel path loss with re-spect to distance and angular blockage factors.
