| Test of hard target and analysis of deceleration-time curves during penetration of double-layers steel targets |
| The testing system which based on the high measure range accelerometer was designed, and then the overload-data which was tested by a hardened subminiature recorder was chalked up and analyzed. The critical lowpass frequency was established and then the overload acceleration was got using Matlab. The results show that the error of data which was tested and analyzed during penetration was less than 10% and the testing system can work during penetration of double-layers targets. |

Abstract The testing system which based on the high measure range accelerometer was designed, and then the overload-data which was tested by a hardened subminiature recorder was chalked up and analyzed. The critical lowpass frequency was established and then the overload acceleration was got using Matlab. The results show that the error of data which was tested and analyzed during penetration was less than 10% and the testing system can work during penetration of double-layers targets.
