Source Identification Techniques — A Critical Evaluation
Experimental methods aimed at source identification continue to evolve. In the last decade, computers, programmable or dedicated, have provided the experimenter with unprecedented data processing capabilities. Highlights of several techniques are presented along with comments regarding limitations and characteristic results.
