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 …
