Abstract: A sensing method and a communication device are provided. The sensing method includes: obtaining, by a first device, at least one sensing measurement result based on an eigenvalue of at least one first matrix. The at least one first matrix is obtained based on a time-frequency domain channel matrix. The time-frequency domain channel matrix includes related information of frequency domain channel responses corresponding to a plurality of time-frequency domain sampling points. Each time-frequency domain channel matrix corresponds to one antenna transmit-receive combination. The related information of the frequency domain channel response is obtained by the first device by performing channel estimation on a received first signal. The first matrix is a covariance matrix or a correlation coefficient matrix corresponding to the time-frequency domain channel matrix; and obtaining, by the first device, a target sensing measurement result based on the at least one sensing measurement result.
