Abstract Almost all military systems use electronic guidance equipments So electronic warfareagainst the electronic equipments of the enemy hinders or weakens their proper operation But most important and most basic step in electronic warfare depends on sufficientknowledge about their radiations and activities in the electromagnetic spectrum On theother hand enemy tries to destroy our electronic systems through intercepting andaggregating information about these systems To detect enemy s measures and maintainour electronic equipments efficiency complete awareness of the environmental radiationsis required To do this it is necessary to intercept all electromagnetic radiations from allpresent emitters in environment via Electronic Support Measures ESM systems But using a single channel by numerous electromagnetic emitters leads to a random interleavedpulse train at the ESM input Therefore it is necessary to de interleave the pulse train atthe ESM receiver After that the analysis of de interleaved pulse trains for identifying theemitters in the environment may be started Any errors in de interleaving step lead toerrors and efficiency degradation in the analysis step A de interleaving algorithm must determine which source produces each interceptedpulse The optimum de interleaving algorithm examines all possible active sourcesequences But high computational complexity of this algorithm makes its implementationpractically impossible In this thesis in addition to describing electronic warfare systems especially ESM systems different methods of pulse train de interleaving are examined Also a new algorithm is proposed that in addition to high efficiency has less complexitythan exhaustive search Also it may be improved to withstand to the problems like missingor spurious pulses new emitters activation present emitters dormancy and time axissegmentation
