摘要

The flying velocity is a key parameter of the projectile in the exterior ballistic test, which is usually measured by the laser screen velocity measurement system. However, how to set the system parameters reasonably to ensure the system capture rate is a challenge due to the insufficient research. In order to solve this problem, our research reveals the change law of the system capture rate by deriving the mathematical model and simulation based on the principle of system detection and the gun firing distribution law. With the three system settings in the simulation, the critical height of the muzzle are 3.78m, 4.1m, and 3.9m respectively. Within the critical height, the system capture rate is greater than 99% theoretically. If it exceeds the critical height, the system capture rate will drop rapidly to 0. In addition, changing the laser power or the arrangement of the detection devices during the test will affect the system capture rate. To verify the simulation result, we perform a gun shoot experiment, fully confirming our analyses.
