Submarine Scattering: Time-Domain Simulation and FFT

Application ID: 55921

This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. Then, a Time to Frequency FFT study is used to transform the results into the frequency domain and the scattered field is analyzed with the Exterior Field Calculation feature.

This model example illustrates applications of this type that would nominally be built using the following products:
