However, in your case, the directivity observed is likely to be dominated by the finite size of transducer (e.g., the recorded signal will be spatially averaged over the transducer surface). In this case, you could start by setting up a simulation where the source (transmitter) and sensor (receiver) masks have the same physical size as given in your datasheet. On transmit, use a single drive signal for all the grid points that form part of each transmitter. On receive, average the signals recorded over all the grid points that form part of each receiver.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulation-of-multiple-ultrasonic-sensor#post-5402 Thu, 25 Feb 2016 06:53:50 +0000 romy_budhi 5402@http://www.k-wave.org/forum/ <p>Hi every one,<br /> The illustration of the position of transmitter and receiver is like in this figure:<br /> [web: "http://i.stack.imgur.com/gTcs6.png"]</p> <p>Could anyone give an enlighten?

It was designed using 3 transmitters and 5 receivers. I used Murata MA40S4R/S<br /> [the datasheet is in: " <a href="https://www.dropbox.com/s/soq050cy4vxns3q/MURATA-zdMURATA_Ultraschall-Sensor-MA_EN.pdf?dl=0" rel="nofollow">https://www.dropbox.com/s/soq050cy4vxns3q/MURATA-zdMURATA_Ultraschall-Sensor-MA_EN.pdf?dl=0</a> " ]</p> <p>I tried to study about Example: Monopole Point Source In A Homogeneous Propagation Medium and<br /> Example: Dipole Point Source In A Homogeneous Propagation Medium</p> <p>But I do not know how to make the directivity graph to be in simulation as in page 4 of the datasheet.<br /> Could anyone help me and give the direction how to simulate those kinds of transmitter and receiver?<br /> Thank you in advance.</p> <p>romy </p>
