sound velocity gradient 中文意思是什麼
sound velocity gradient
解釋
聲速梯度-
Compared with the pressure hydrophone, vector transducer can provide both the information about pressure ( scalar quantity ) and particle velocity ( vector quantity ) of the sound field, which offers more possibilities for signal processing. so vector transducer and its signal processing have attracted the attention of researchers both native and foreign. in this thesis, a method of correlation equations for pressure gradient transducer is presented, and the estimation of multi - signal parameters with single vector transducer is given
與傳統的聲壓水聽器相比,矢量水聽器既能獲得聲場中的聲壓這一標量信息,又能獲得聲場中質點振速這一矢量信息,這為其信號處理帶來更大的空間,因此矢量水聽器及其相應的聯合信息處理技術日益成為國內外科技工作者們研究的熱點。 -
