Position parameters were obtained from the simulation with the model of towed array.Based on the theory of radiated noise forming, the launch noise was simulated according to test condition in Laboratory,and the result showed the launch impulsion noise obeyed SαS distribution. The simulated noise attenuating in deep sea was analyzed with a sound loss translation model.Minimum variance distortionless response,spatially smoothed MVDR, and beam-space multiple signal classification algorithm were adopted to process the signal, hence the source level, the frequency structure and the location of the launch noise were achieved.
