主要闡述了聲定位技術的基本原理及輕型自動報靶設備的系統設計，論述了該系統與框型布陣設計的差異，以及在應用推廣方面的優缺點。該設備以實現輕型、便攜的電子報靶為目的，采用了等距線性布陣的原理及嵌入式設計的方法，較好地解決了自動報靶設備防護面積大、價格昂貴、不便于在野外使用的缺點，該系統通過實彈檢驗，能夠滿足測量精度要求。因此該設計可行，有著較好的應用前景。

　　Abstract:

　　It is introduced about principle of acoustic orientation and system design of auto_check bullet location. The difference of frame sensors’ location and linear sensors’ location is pointed out in this paper. The advantage and disadvantage of application is telled. In order to designing a portable intellectual electronic device， the system adopt a principle of isometric linear sensors’ location and a design of embed. The new design have solved the problem about fence area， expensive price and inconvenience in outdoors application. According to the result of measurement in shot， precision of the device is achieved. Based on the experiment， the design is feasible and the device can widely be applied in auto_bullet location.
