关于提高《弹丸飞行初速测试实验》课程实施可靠性的探讨

摘要

弹丸飞行初速的测量是一项经常性的工作,在培养装备保障和指挥类人才中,弹丸飞行速度的测量是学习的重要内容之一.雷达测速法是诸多测量方法中的一种,由于测速雷达适用武器范围广、不受场地限制及在高射角射击时架设方便等优点,得到了广泛应用.在某初速雷达的教学实施使用过程中,发现该雷达的可靠性不够高,尤其在测量小口径弹丸的飞行初速时经常得不到可靠数据.本文对该初速雷达的测速原理进行了简要论述,对存在的问题进行了详细的分析,提出了改进措施.经验证,改进后可有效提高某初速雷达的测试可靠性.%Radar-testing-speed is one of many bullet muzzle velocity methods which is often used. It is applied widely because of its excellences, for example, it is for a wide range of weapons and environments, convenient to use in a large angle when shooting. In the employing of the muzzle velocity radar, we find that its reliability is not enough, especially when we test the muzzle velocity of a small-caliber projectile. In regard to the muzzle velocity radar, we make the reliability of muzzle velocity radar better by making a simple exposition for its speed-testing principles, a detailed analysis and improved measures for problems.
