Executive Summary

In a dense modern electronic warfare environment, IFF/SSR systems receive a wide range of signals from existing radars. Among the most important tasks of such systems are recognition of signals, extraction of work modes for each of the present objectives, separation of received signals, their classification and identification of friend or foe. Because of the equality of the frequency of interrogation signals, the similarity of pulse width in IFF/SSR Radars, and the lack of accuracy of the pulse amplitude as a proper criterion for classification, it is necessary to use a suitable algorithm for de-interleaving and clustering of such radars.
