针对现有军标中规定的炮口冲击波等压场测试方法不适用于某型舰炮炮口冲击波压力场的测试情况，提出了以极坐标布放传感器的测试方案，并测试了各点位的冲击波超压值。其次，提出采用三次样条函数方法对测试数据进行插值；最后，使用Delaunay三角划分方法对插值后的数据进行网格划分和等压线绘制，得到了某型舰炮的炮口冲击波等压场。

According to the muzzle shock wave measurement method provided by existing military standard is not suitable for a certain type of naval gun,the measurement scheme based on polar coordinates distributed sensors was presented,and the muzzle shock wave overpressure of each position was measured. Secondly,the interpolation curve pressure field was achieved using Cubic spline interpolation function. Finally,the drawing method of contour line based on Delaunay triangulation was adopted,and obtained the muzzle pressure field of a certain type navel gun.
