Sonar simulation with 3 microphones with LabVIEW


Use this VI to simulate a Sonar made up by three microphones



Simulates acoustic bearing (range and angle) estimation on an 180 degree arc. The true target follows a semi-circle of defined radius. The delays are estimated using the PHAT algorithm (phase-transform based on generalized cross-correlation). The microphones are in a straight line normally the same distant apart. The reference mic is the centre one assumed to be at (0,0).



  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

1. Open Main.vi

2. Select scan radius
3. Run Main.vi
