    Abstract: A description of calibration methods of vector receivers in the frequency range 5 Hz to 10 kHz and comparison verifications are given here. At the low frequencies, the vertical and horizontal standing wave tube methods can be used for calibration of vector receivers. At the high frequencies, free-field reciprocity method and comparison method can be used for calibration. To verify the calibration methods, a pilot comparison calibration of vector receivers was performed between Hangzhou Applied Acoustics Research Institute (HAARI), China and Russian National Research Institute for Physicotechnical and Radio Engineering Measurements (VNIIFTRI). The vertical standing wave tube comparison method working in the frequency range 5 Hz to 400 Hz and free-field three-transducer spherical-wave reciprocity method working in the frequency range 500 Hz to 10 kHz were used for calibrating of three vector receivers VHS56, VHS90 and KGP-10. From the calibration results, the veracity of two calibration methods was proved effectively, no significant discrepancies were detected within these comparisons.
