Hi Sir,

I am using k-Wave for modelling underwater target for acoustic 3D imaging. I placed a target (ball of radius 25mm) of density 8000 kg/m^3 and acoustic speed 6000 m/s in water medium at a distance of 20cm from the sensor array. I am using kspaceFirstOrder3D function and the source strength is 100e20 Pa. But I am not getting a significant reflections from the target. How can I improve the reflections? Please help me.

Regards,
Mimisha

Hi Mimisha,

Such an object should reflect. You have a source pressure of 10 000 billion GPa? That would be a problem if you have set the nonlinearity parameter to something nonzero.

Best wishes
Ben
