A multifunctional radar (MFR) with varying pulse sequences can change its signal characteristics and/or pattern, based on the presence of targets and to avoid being jammed. To take a countermeasure against an MFR, it is crucial for an electronic warfare (EW) system to be able to identify and separate a MFR’s modes via analyzing intercepted radar signals, without a priori knowledge. In this article, two correlation-based methods, one taking the signal’s order into account and another one ignoring the signal’s order, are proposed and investigated for this task. The results demonstrate their great potential.
