Determination of optimum positions for sensors in acoustic pyrometry system by successively eliminating sensors having minimum independent effectiveness from an initial arbitrary array

摘要

Sound sensors are initially deployed arbitrarily (S1) on a rectangular section. A transfer matrix (S2) is prepared and effective independence values are found for all paths (S3) by making a singular value decomposition from the transfer matrix. A total effective independence value for each sensor (S4) is found from the path values and sensors having minimum values are successively eliminated (S5) down to a target sensor number
