Is your object too small? Start with a simple setup, perhaps in 2D and check you can get that to work. Copy the examples in the toolbox to help.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/regarding-source-strength#post-8522 Thu, 28 Apr 2022 08:13:43 +0000 122014006 8522@http://www.k-wave.org/forum/ <p>No. I set alpha_coeff = 0.0022; % [dB/(MHz^y cm)] and alpha_power = 2;<br /> I also tried by setting alpha_coeff = 0.0000;. But the same issue persists. What is the possible solution for this? </p> http://www.k-wave.org/forum/topic/regarding-source-strength#post-8506 Mon, 25 Apr 2022 19:08:55 +0000 bencox 8506@http://www.k-wave.org/forum/ <p>Do you have the absorption set too high or are you adding an unrealistic level of noise relative to your source amplitude? </p> http://www.k-wave.org/forum/topic/regarding-source-strength#post-8469 Tue, 08 Mar 2022 05:17:33 +0000 122014006 8469@http://www.k-wave.org/forum/ <p>I am trying to use K wave for Sonar imaging simulations. I need to receive reflections from 2 or 3m away from the sensor array. But I don't get a significant amplitude from 1m or even 10cm. How can I over come this problem? Is there any provision to increase the strength of the transmitted signal beyond a level in k wave? Suggest me any other option which will help me to get significant reflections from this range. I am using a 3D kwave grid. </p>
