In the process of developing guided missile for high frequency firing of naval gun and intelligent transformation of conventional missile, the measurement of various key indicators invisible in the firing process is very important for the control of the whole firing process and the measurement of endurance limit performance of naval gun. This design is based on IPC sensor, MEMS high-precision gyroscope and other sensors to design sensor array to collect in-bore process data. This design uses FPGA as the main control chip and controls the multi-channel high-speed ANALOG-to-digital conversion circuit to achieve the dynamic test of the firing chamber of naval gun and guided ammunition in a very short time period. After passing the SRAM cache, it is written into the eMMC storage system. The recorder realizes 8-channel 40MS/s sampling rate of analog signal and 2-channel digital signal acquisition, and realizes 250MB/s data storage. And can meet the impact overload within 50000g, 12000°/s angular rate of harsh environment dynamic test, error is less than 1%, can meet the very short time of harsh environment dynamic parameter measurement.
