摘要：Munition's velocity measuring device is the key to realize accurate strike, its measuring accuracy and the reliability of whole system have great influence on the effect of munition's air-burst. A muzzle velocity measuring device with dual-excitation coils is proposed, which is adapted to small arms grenade launchers. The electromagnetic model of the velocity measuring device based on the principle of electromagnetic induction is established, and the theoretical expression of its signal is given. Factors affecting the signal are analyzed in MATLAB, through which conclusions of device's structural parameters, the turns of coils, and the carrying current of excitation coils, etc. are drawn.
