Title  Aluminum foil target signal conditioning and data processing software design                                           
Abstract
In the evaluation of warhead’s performance in combat need to measure flying speed ,spread and attenuation of fragments after static and dynamic burst experiment .Aluminum foil target designed to be used for field measurements of velocity fragments group multi-channel signal conditioner. Design including the size and shape of the chassis design, board layout drawing, and PC data processing software to write. Power supply can be 220V power supply, can also be suitable for field work required, the use of dry battery, chassis panel can display the connection status of foil target, the output signal can be easily connected to the system and data acquisition, and deliver the pulse which is through the target to data acquisition system. With the multi-channel data acquisition system can easily capture multiple speed signal, the method of data collection by the direct recording output signal fragments over the target, or use artificial intelligence algorithms to identify desired measurement signal, instead of measuring instrument recorded between the two signals time interval, to achieve fragments measuring speed. the Pro/E as an engineering drawing software, and Protel using to draw the board, LabVIEW using in preparation of PC data handler are mainly used in design.
Keywords :Aluminum foil target ,Signal conditioning ,Data processing ,
