The Design Method to Velocity Measurement of Tracer Bullet Based on Laser Screen Target

In view of the question that the date of velocity measurement is inaccurate when tracer bullet is measured based on laser screen target, on the basis of analysis the luminous mechanism,the paper present a method of tracer bullet velocity measurement based on laser screen target, and acquire a velocity measurement system by using the construction principle of laser screen target field of view detection. First of all the measurement systems devise the test device for tracer, and fast acquire two shape signals and two tracer signals match with the laser screen targe' lighting apparatus and receiving device, then, calculate the flight speed of tracer bullet by way of velocity measurement algorithm. The measurement system has been certified in the velocity-measuring experiment of gunshot, the principle and method is feasible. The measurement system can not only measure tracer bullet's velocity but also measure non-tracer mode bullet velocity.
