| Abstract: | The aerodynamic theory shows that the shock-wave of flying super-sonic projectile is generated for the projectile compressing and expending its ambient atmosphere. This paper analyzes physical characteristic and spectrum characteristic of shock-wave and the sensor frequency response, sensitivity, overload and entire tropism capability of measuring shock-wave signal. This paper provides scientific basis for collective device of gun antiair shooting acoustic target system. |
