The Doppler Radar Measurement of the Velocity of 12.7mm Duplex Ammunition
In this paper, the constitution and experimental results of a Doppler radar velocity measurement of duplex ammunition are introduced .The exist various sensing device test techniques are reviewed and some limitations used in duplex-ammunition velocity measurement are pointed out. Based on the mentioned above, the Doppler radar velocity measurement has been put forward to measure the velocity of both bullets of duplex-ammunition in the full trajectory. By means of the Doppler radar method, the fault of the aft bullet could be found, and therefore its structure was changed. In virtue of improvement of the structure shape of the aft bullet, its drag coefficient was reduced, and the 1000 m velocity fall was decreased and the armor-piercing power could be reached.
