The Research On Equipment System Of Vector Sensor Calibration

Vector sensor is a especial kind of sensor with little dimension and more channels. According to using vector sensor technology is the important method that efficiency solve the difficult problem of increasing low frequency faintness measure signal's Signal-to-Noise in the course of the field of engineering application in our country at present. Vector sensor calibration equipment system can ultimated solve the problem of vector sensor terminal Science measure Calibration, it is established strong calibration base on the technology development of submarine's damping an debase noise for our country with the important martial application value and economic value.Firstly, this paper briefly analyzed the face to the characteristic and the compare calibration theory of vector sensor in the water, expatiate and analyzed the calibration theory of vector sensor and the needed calibrated parameter, research and confirm the calibration method and the messure error rules of calibration equipment system, definitude should adopt correct messure method of the calibration messure of vector sensor in actual sound field.Secondly, on the base of researching and analyzing above, this paper emphases researched the calibration messure method and equipment system of vector sensor with air,pool and test-bed of the water acoustics. Establish the calibration equipment system can provide sensitivity messure result of vector sensor, channels directivity parameter messure result and the characteristic of output voltage and phasic, besides analysis the calculate error.In this paper the established calibration equipment system of vector sensor is provided with measure precision, low devotion, use facility and so on, it is easy to popularize and extend in actual messure work, this is not only satisfy the requirement of the messure technology's of submarine's radiated noise's application and development, but also solve the actual problem of vector sensor's periodic calibration in our country at present.
