关 键 词：DOA Reliability Evaluation of ESM Deinterleaver Based on Sorted DOA Difference ESM 

摘      要：In order to evaluate the reliability of deinterleaving results in Electronic Support Measure (ESM),this paper presents a separability test method referred to as Sorted Direction of Arrival Difference Test (SDOADT) and introduces the concept of Confidence Level of Direction of Arrival (CLDOA).Theoretical analyses and experimental results show that,SDOADT has the ability to examine the separability of each pulse cluster obtained from ESM deinterleaver,and its resolution of test increases rapidly with the augment of the pulse *** addition,the index of CLDOA gives a good assessment to confidence degree of the considered pulse cluster in the DOA *** the information about deinterleaving reliability can be achieved via the proposed methods.
