| 针对常规武器火炮直瞄射击时的弹着点测试问题，提出了一种双圆环形传声器阵列方法，该阵列将若干传感器布设在两个圆环上。并根据超音速弹丸产生的激波传播速度随传播距离增加逐渐递减的规律，对每个传声器阵分别引入一个视速度，建立了双视速度模型。通过计算机仿真分析表明，采用双圆环形传声器阵列及双视速度模型确定弹丸弹着点坐标，带来的模型误差优于3mm，对于工程应用而言可以忽略。试验结果表明，双视速度模型明显优于将激波传播速度视为恒定的基本模型和交会模型。 |

| Aiming at the problem of the impact point test of the conventional weapon artillery direct shooting, a double-circular ring microphone array method is proposed，which places a number of sensors on two rings. According to the law that the shock wave propagation speed is gradually decreasing, a visual velocity is introduced for each microphone array, and finally a double apparent velocity model is established. The simulation analysis shows that when the double apparent velocity model applies to calculate the target coordinates, it will bring the model error less than 3mm, which can be ignored for engineering applications. Moreover, the test results show that the double apparent velocity model is significantly better than the intersection model and the basic model which is regarded the shock wave propagation speed as constant. |
