Design of automatic measurement system for direct fire shell impact point

Abstract

Aiming at the problems of traditional manual detection of gun firing, such as hidden danger, poor accuracy and low efficiency, this paper proposes an automatic measurement system for the impact point of direct fire shell. Based on the acoustic positioning principle, collimation noise shielding technology based on slit, distributed sensing and coordinate conversion method, the impact is realized by integrating the time difference of shock wave arrival and the geometric relationship between sensors the accurate detection of points can improve the rapid detection ability of artillery performance test and firing training.
