Shock wave and muzzle wave are the main acoustic signals after the gunshot. This paper analyzes the two acoustic signals,selects a microphone array for acoustic measurement and designs a sound source location algorithm in two-dimensional space.
马赫波和爆轰波是狙击步枪激发后产生的两个主要的声波信号,本文对这两种声波信号的特征进行了分析,并针对信号的特征选择了用于声源定位的麦克风阵型,设计了二维空间的声源定位算法。

速度升高到1.3马赫（速度单位，1马赫=音速=340.29m/s——译者注）以后，不会再对冲击波强度造成太大的影响。
Increasing speeds above Mach 1.3 results in only small changes in shock wave strength.
这种汇合（或马赫）波的性质与前面所叙述的一般冲击波相同。
The behavior of this fused or Mach Wave is the same as that previously described for blast waves in general.
另外，推测了马赫数4拟似冲击波非对称的原因。
Moreover, the reason that Mach 4 oblique shock wave is asymmetric is conjectured.
