Source location error analysis and optimization methods

摘要: The efficiency of an optimization method for acoustic emission/microseismic (AE/MS) source location is determined by the compatibility its error definition with errors contained in input data. This can be examined terms distribution station residuals. For ideal distribution, held at where it takes place as residual and not permitted to spread other stations. A comparison study two methods, namely least squares absolute value method, shows that this character constrains minimizes their impact, which explains much more robust performance dealing large isolated errors. When data are systematic and/or extreme basic structure altered these errors, none methods able function. only means resolve problem early detection correction through a screening process. An efficient process primary importance AE/MS location. In addition critical role those creates favorable environment applying methods.
