Recently, integrated sensing and communication (ISAC) has attracted substantial research efforts and been deemed as a major scenario of 6G. To support the study and standardization of ISAC, sensing channel modeling is rather critical. In this paper, we demonstrate the latest sensing channel measurement results, in which the sensing pathloss is particularly focused. In principle, we adopt a cascaded sensing pathloss model, inherited from pathloss model in 3GPP TR 38.901, by considering the radar cross section (RCS) of the sensing target. Further, we conduct the sensing channel measurements with an ISAC prototype in the indoor hotspots (InH) and urban micro (UMi) scenarios, in which the sensing pathloss is focused. The sensing signal in the measurements is configured based on the new radio (NR) protocols, to accord with practical application. The specific path corresponding to the sensing target is identified to obtain the sensing pathloss, through the signal processing method in the delay-doppler domain. From the results, the cascaded sensing pathloss model is shown to fit well with the measurements at acceptable deviations. This work preliminarily verifies the feasibility of sensing channel modeling based on the 3GPP TR 38.901 channel model in field test on prototype, for the first time to our best knowledge.
