In order to improve precision of trajectory identification and speed of trajectory calculation

design a trajectory parameters measuring system based on C8051F352. It accomplishes the trajectory parameters such as initial velocity and angle of fire identification through the process of gathering

saving and dealing with the dynamic pressure and static pressure information. This system regards C8051F352 as processor unit

and it uses the differential pressure sensor and absolute pressure sensor

trajectory identification method based on dynamic pressure and static pressure is used to raise the precision of trajectory parameter measurement. Experimental test result indicates that this system has high measurement precision and fast calculating speed

which satisfies requirement of trajectory identification.
