Influence of Accuracy of Continuous Wave Doppler Radar on Muzzle Velocity Evaluation

炮口初速本质上是一个随机变量,需要射击一定数量的弹丸才能确定置信区间及置信度,连续波雷达作为测量初速的重要设备,其精度影响初速试验估计的用弹数量,文中对初速测量进行参数估计,计算初速置信区间及其置信度,并考虑雷达测速误差对初速估计的影响,讨论射弹数量与雷达精度的关系,以期选择最少的用弹量准确考核被试弹药性能,降低试验成本,提高试验效率。

Muzzle velocity is essentially a random variable measured in conventional weapon testing domain , confidence interval and confi-dence level of muzzle velocity are calculated by firing a quantity of projectiles , as main equipment , accuracy of continuous wave Doppler is an important factor influencing quantity of projectiles used in test range .Muzzle velocity was evaluated in this paper , confidence interval and confidence level were calculated , and error of measurement of the radar was evaluated for velocity accuracy , the relation between quan-tity of projectiles and radar measurement accuracy was discussed in order to cut down consumption of projectiles , and increase efficiency of firing accuracy measurement , the minimum projectiles were fired for evaluating ammunition .
