| 摘 要： | 针对大口径机枪双头弹的运动特点，提出了一种采用多普勒测速雷达实现两目标测速的实验方法，进行了多普勒测速实验，获得了双头弹１００ｍ内全弹道速度－时间关系曲线。并计算出了双头弹两个弹头的切速和此道段的阻力系数，据此进行了行特性分析。实验结果证明，大口径机枪双间两个弹头的飞行是稳定的，且两者之间存在相对比较固定的速度差。该测试结果为其弹道分析提供了可靠依据。

| Abstract: | A test method for obtaining duplex ammunition's velocity using Doppler radar is presented in light of large caliber duplex ammunition's flight characteristics. Doppler radar test has been carried out, which achieved velocity time relation curves of the duplex ammunition within 100m range. Initial velocities and drag coefficients of the two bullets of the duplex ammunition have been calculated and the flight characteristics analyzed. The test results prove that the two bullets are stabilized and there is a fairly fixed velocity difference between them. The method is practical and the results are reliable for ballistic analysis. |
