Oriented to the technique implementation and standardization establishment of ISAC, a measured ISAC sensing signal dataset is constructed based on 5G air interface. This dataset uses a universal software radio peripheral to run the 5G New Radio (NR) physical layer protocol stack, in which the downlink demodulated reference signal is reused as the sensing signal to execute the data acquisition, including 2 scenarios and 2 sensing modes, totaling 8 groups of data. In each scenario and each sensing mode, channel information of 8 channels in continuous 30 seconds is provided containing both moving sensing target and background environment, and data corresponding to only background environment is also provided. For clearer demonstration of the dataset, this paper shows the delay spectrums and delay-Doppler spectrums of typical sensing signal through the classical 2-dimensional discrete Fourier transformation (2D-DFT) algorithm with corresponding analyses and descriptions. Furthermore, this paper provides a reference path method in the delay domain based on the oversampling inverse discrete Fourier transformation (IDFT) algorithm to suppress the sensing idealities in bi-static sensing, to verify the reliability and effectiveness of the dataset.
