Abstract
Methods and systems for locating a chemical source include measuring chemical concentration with sensors at a plurality of different positions. Measurements from pairs of positions are cross-correlated to determine an average velocity vector for a group of positions. A convergence region is determined based on a plurality of average velocity vectors to determine a chemical source location.
Claims20
A computer-implemented method for locating a chemical source, comprising:
- measuring chemical concentration with sensors at a plurality of different positions;
- cross-correlating measurements from pairs of positions using a processor to determine an average velocity vector for a group of positions that averages away turbulence contributions;
- and
- determining a convergence region based on a plurality of average velocity vectors to determine a chemical source location.
