摘要： An apparatus for use in a firing range, in which transducers located adjacent the target area detect the airborne shock wave from supersonic projectiles. The position at which each projectile passes through the target plane is determined from the relative time of arrival of the associated shock wave at the transducers. A visual display of the target and the projectile position is provided for the use of range personnel.

摘要： Transducer assembly having a head and a transducer element contacting the rear of the head.In order to provide an output signal from the transducer element which has a positive value over a wide range of angles of incidence of shock or pressure waves to be detected by said transducer assembly, the transducer element contacts with the rear of the head over a zone which is smaller in cross sectional area taken perpendicular to the direction of propagation of the shock or pressure wave through the assembly than that of the rear of the head. In order to provide electrical connection to the front face of the transducer element which can be a piezo-electric element, it can be mounted in a metal tube with a partly closed end which electrically contacts the front face of the element. In order to positively position the transducer assembly and to inhibit unwanted shock or pressure waves reaching the element, the assembly has a series path of four interfaces of acoustic mismatch of shock or pressure waves, between said head and a body.

摘要： A curved, elongate transducer assembly contacted by a shock or pressure wave transmits the resultant vibrations to the ends of the member, the vibrations at the respective ends being converted to output signals from which a time difference signal is produced. A computer calculates from the time difference signal the inclination angle of the projectile trajectory relative to a reference line. Two of the curved, elongate transducer assemblies at spaced locations permit calculation of two such inclination angles and, therefrom, the location at which the projectile trajectory passes through a reference plane. The transducer assembly may be a rigid bar with transducer elements at each end, or a single piezoelectric member with pickup electrodes at each end. Two transducer assemblies may be housed in a lower portion of a framework covered with a target sheet of penetrable material to form a chamber, in which case the location at which the trajectory of a subsonic projectile passes through the target sheet may be determined.
摘要翻译：由冲击波或压力波接触的弯曲的细长的换能器组件将所得到的振动传递到构件的端部，各端的振动被转换成产生时间差信号的输出信号。计算机根据时差信号计算射弹轨迹相对于参考线的倾斜角度。在间隔位置的两个弯曲的细长的换能器组件允许计算两个这样的倾斜角，并且由此计算射弹轨迹穿过参考平面的位置。换能器组件可以是在每个端部具有换能器元件的刚性杆，或者在每个端部具有拾取电极的单个压电元件。两个换能器组件可以容纳在被目标可穿透材料片覆盖的框架的下部中，以形成腔室，在这种情况下，可以确定亚音速弹丸的轨迹穿过目标片材的位置。
