Overview
Use this VI to simulate a Sonar made up by three microphones
Description
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).
Requirements
Steps to Implement or Execute Code
1. Open Main.vi
2. Select scan radius
3. Run Main.vi
