    • In a moving body inspection apparatus, sequential waveform data obtained from a movement sensor is analyzed, wherein a plurality of waveforms from the waveform data is generated; phases compared among a plurality of movement waveforms; and a result of comparing phases are displayed. A partial waveform in a frequency analysis time interval having a predetermined length is extracted from a plurality of the movement waveforms. A frequency analysis operation is performed for the extracted partial waveforms to calculate phases at maximum power frequencies in the frequency analysis time interval; a phase difference is calculated among a plurality of the movement waveforms. The peaks may be detected in a plurality of movement waveforms. Peak intervals are calculated between adjoining peaks which adjoin each other in time base out of the peaks. The peaks among the movement waveforms are matched. Phase differences are calculated among a plurality of the movement waveforms.
