Deinterleaving For Radar Warning Receivers

Modern radar warning receivers form the clusters by processing the incoming pulses using multiple parameter deinterleaving. Validation and identification of formed sequences obtained from formed clusters are made by time-of-arrival (TOA) deinterleaving. Especially, validation and identification of the sequences utilizing as minimum number of pulses as possible are of utmost importance. The improved method presented in this paper focuses mainly on identifying the sequence having small number of pulses with a possibility of missed pulse. The algorithm uses the predefined pulse repetition interval (PRI) range during TOA deinterleaving to tackle the aforementioned situations.
