Aiming at problem that airy acoustics miss distance measurement cannot achieve three-dimensional localization currently

propose a new idea of vector sensor. A new embattle scheme is designed that based on vector voice sensor

and this scheme realize DOA estimation of object making use of voice pressure and vibration speed cross-power

and it brings about object three-dimensional localization of multi-array with probability density distribution. Simulation experiment prove that this scheme can solve the problem of acoustics miss distance threedimensional localization

and precision of localization meets request.
