Design of a bomb-borne solid-state recorder for high-shock test and its application

A bomb-borne solid-state recorder was proposed to record the explosion-induced high-shock signals.In this solid-state recorder, the FPGA device XC2S30 is used as the core controlling chip.With the joint function of the A/D controller, the high-speed state machine, the phase-delayed clock and the flash memory controller working in the recorder, it can transform the high shock signals into digital ones and store them into the main memory which is made up of flash memory. With the multi-layer cushions and double-walled steel structures, the high-shock signals for the whole dispersal and gunfire tests were successfully recorded by applying the proposed solid-state recorder.
