However, it might become a bit of an indexing nightmare calculating the input signals if you want your sources to move in an arbitrary way. You could try by following the example Ben mentions above.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulate-moving-medium#post-5088 Tue, 26 May 2015 09:28:57 +0000 Guy_L 5088@http://www.k-wave.org/forum/ <p>Hi Ben,</p> <p>that example did help, thank you.<br /> in that example, is it possible to create two sources with different parameters (velocity, frequency and location)?</p> <p>Thanks!<br /> Guy </p> http://www.k-wave.org/forum/topic/simulate-moving-medium#post-5078 Sun, 10 May 2015 19:45:54 +0000 bencox 5078@http://www.k-wave.org/forum/ <p>Hi Guy, </p> <p>No, we don't support moving media at this stage. But of course you could measure a frequency difference between two signals. You don't need k-Wave just some way of taking a Fourier transform.</p> <p>Does <a href="http://www.k-wave.org/documentation/example_tvsp_doppler_effect.php">this example</a> in the Toolbox help? </p> <p>Ben </p> http://www.k-wave.org/forum/topic/simulate-moving-medium#post-5073 Wed, 06 May 2015 15:58:02 +0000 Guy_L 5073@http://www.k-wave.org/forum/ <p>Hello, (sorry for bad english)</p> <p>I'm trying to simulate a moving medium (at least part of it) and determine the speed of that moving parts by the Doppler effect.</p> <p>Can i simulate the movement by "just" adding 4th dimension (time) to the medium matrix?<br /> and also, does the K-Wave support measuring the frequency difference?</p> <p>Any help and/or suggestion will be welcome<br /> Thanks!<br /> Guy </p>
