A method of Radiation Source Identification based on DST-IFS

摘要

Aiming at the current complex electromagnetic environment, radiation informations obtained by different sensorsare different, resulting in different identification confidence levels. Based on the abundant analyses on evidence weight measurement on information confidence, this paper applies the original evidence of decision-making to assign values to intuitionistic fuzzy membership and nonmembership under the DS framework, and then makes decision based on intuitionistic fuzzy decision -making methods, and proposes a radiation source identification method based on a combination of DS evidence theory and intuitionistic fuzzy set (Dempster-Shafer evidence theory-intuitionistic fuzzy set, DST-IFS). Experiments show that this algorithm can meet the actual requirements on confidence difference of information obtained by multiple sensors under complex electromagnetic environment, and improve the accuracy rate of radiation source identification results.
