It is often formed cluster environment when projectile firing against air targets, and from the cluster to extract projectile shock information as a major problem. Based on the analysis of the impact of projectile shock wave and the environmental impact of the projectiles, the method of decomposing the projectiles into linear and nonlinear is proposed. The problem of shock wave encounter is decomposed into the outside problem and the interior problem, the method of shock wave separation based on image plane and virtual sound source is studied. The parameters such as the amplitude, phase and amplitude of the sound pressure in the air shock wave of the projectile are simulated and captured. The results show that the spectral peaks are distinct, the resolution is good, and the sound pressure and phase are described in detail.
