In order to obtain the acceleration signal of the projectile under high overload conditions in the bore, a missileborne data acquisition system was designed. The highperformance Zynq7000 series SoC chip is selected as the control core, which combines with the programmable A/D conversion chip and large capacity Nand Flash memory, to complete the data acquisition. Through the comprehensive potting technology of the finished circuit board, the overall impact resistance of the system is improved. Through the analysis of the measured results, it is shown that the system can accurately obtain the change curves of the acceleration of the projectile.
