Integrated Sensing and Communication (ISAC) has been considered a promising technology in the sixth generation (6G) system. An accurate channel model is a prerequisite for ISAC system design. This paper presents the first sensing and communication channel measurement campaign in typical indoor factory (inF) environments at 28 GHz and 38 GHz, in which over 720 spatial channel impulse responses are collected. The power-delay-angular profiles of multipath components are obtained, and the shared scatterers in communication and sensing channels are intuitively observed. A cluster centroid distance threshold-based cluster identification algorithm is novelly proposed to extract shared clusters from measured ISAC channels. Finally, the sharing proportional coefficient (SPC) is defined to measure the sharing feature of the ISAC channel. Results show that the channel SPC has an upward trend as the frequency increases. The observations presented in this work will offer promising support for ISAC wireless system evaluation.
