In the research of uncertain information processing,Dempster-Shafer Theory(DST)provides a framework for dealing with uncertain information,where evidence is defined on a Frame of Discernment(FOD)consisting of mutually exclusive ***,the requirement of exclusiveness on FOD sometimes is not satisfied,as shown in Dezert-Smarandache Theory(DSm T),a derivative of *** DSm T,the non-exclusiveness is expressed by propositions’intersection and the fusion of evidence is realized through a proportional conflict redistribution(PCR)*** order to handle non-exclusive FODs,a new framework called D Number Theory(DNT)has been proposed recently,which quantifies the non-exclusive degree between propositions different from DSm *** previous studies,an Exclusive conflict redistribution(ECR)rule has been designed in DNT to implement the fusion of evidence defined on a non-exclusive FOD,but there are some deficiencies in the ECR *** this paper,a new rule called ECR-PCR rule is proposed by combining the ECR and PCR rules to better implement the fusion of evidence defined on a nonexclusive *** the proposed rule,the definition of conflict utilizes the idea of ECR’s exclusive conflict,and the disposal of conflict is following the idea of PCR’s proportional *** of the ECR-PCR rule are *** effectiveness of the proposed new rule is verified through numerical examples and applications,in comparison with other fusion methods.

An Improved Radar Emitter Recognition Method Based on Dezert-Smarandache Theory

引用

Chinese Journal of Electronics 2015年第3期24卷 611-615页

作者： CHEN Changxiao HE Minghao LI Hongfei Air Force Early Warning Academy

The parameters of radar emitter are fast changing in the current complicated electromagnetic environment, and the radar emitter recognition rate which used single sensor method cannot satisfied. To solve the problem, an improved radar emitter recognition method based on Dezert-Smarandache theory is proposed, which can improve proportional conflict redistribution rule to solve fuzzy and conflicting information from radar emitter. Some examples are given to show the validity of the improved method.
