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.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/not-getting-proper-reflections-from-a-target-placed-at-20cm#post-8521 Thu, 28 Apr 2022 08:05:18 +0000 122014006 8521@http://www.k-wave.org/forum/ <p>Hi Sir,</p> <p>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.</p> <p>Regards,<br /> Mimisha </p>
