| 中文摘要: |
| 目前用于确定弹丸或导弹落点的声测方法多数是基于这样一个假定：其所发出的声波是一个平面波。但当其下落速度大于声速时，这个假定就不成立了。这时产生了一个锥面激波［４］，本文介绍一种利用正方形基阵对其进行测量的方法。 |
| 英文摘要: |
| Most methods used for determining the point of impact or points on the trajectory of a shot or missile using sound-ranging data are based on the assumption that the acoustic wave is a plane wave. Yet when its falling speed is supersonic, this assumption is no longer valid. Since the missile generates a cone-shaped shock wave. This paper introduces a new approach to locate the missile by using a four microphone square array. |
