This work is to present a method to verify the reliability of the device for the measurement of pressure in near field. We put forward the verifying method of comparing the transmitting attenuation curves in the spherical field measured by the element hydrophone with that in an ideal spherical field. The distance between the source and the hydrophone is revised by the spherical source's center computed by least-squares fit. Trait of weak scattering field is established. So we arrive at the conclusion that this device can scan an extremely near field of range less than one-seventh wavelength.
