PROBLEM TO BE SOLVED: To provide a sensing method and sensing device capable of reducing DC offset caused from high-frequency signal used in wireless communication with a simple configuration to prevent deterioration of target sensing characteristic.SOLUTION: In an M-th transmission group and an (M+1)-th transmission group which includes 2N transmission periods, a control section 402 determines a phase rotation amount in which the phase rotation amount given every two transmission periods is inverted by 180 degree in the M-th transmission group as a phase rotation amount given every two transmission periods in the (M+1)-th transmission group. A phase rotation section 410 gives the determined phase rotation amount to the generated transmitting signal at every transmission periods. A transmission RF section 230 converts transmitting signal after the phase rotation to the high-frequency signal and transmits the signal through transmission antenna. |
