舰炮测速雷达是配置在军舰上的测量舰炮弹丸初速的测速传感器。由于军舰的运动,使雷达测量的速度发生了一些变化。本文分析了影响舰炮弹丸初速的因素,推导了舰炮弹丸速度方程。分析认为:雷达测量的舰炮弹丸相对初速基本不受舰体运动的影响。在采用现代导航技术的情况下,绝对初速测量精度优于0.l％。 Naval gun speed radar is configured on the warships to measure the gun speed gun velocimeter velocity sensor. Due to the movement of warships, some changes have taken place in the speed of radar measurements. This paper analyzes the factors that affect the initial velocities of naval gun projectiles and deduces the velocity equations of naval gun projectiles. The analysis shows that the relative muzzle velocity of naval gun measured by radar is basically unaffected by the hull movement. In the case of modern navigation technology, the absolute velocity measurement accuracy of better than 0.1%.
