For projectile flight attitude measurement, the problems with real-time processing and analysis processing, the half hard-recovery of FPGA and microcontroller are complex structure, larger volume and poor operation. As for the projectile at high speed and under high overload environment, a projectile flight parameter acquisition and hard recovery system was designed based on TMS320F28335 and composed of sensors, ADC, DSP chip and memory chip so as to achieve projectile dynamic information acquisition, processing and storage. The test shows the system can completely and accurately obtain various parameters in the projectile flight parameter test process. The system can provide a strong basis for the projectile flight parameter test.
