Reconstruction of Radar Pulse Repetition Pattern via Semantic Coding of Intercepted Pulse Trains

The timing structure of multiple successive radar pulses constructs a high-dimensional pattern for intercepted pulse trains, which is called as repetition interval (PRI) pattern. By treating the machine that uses differently permuted to communicate with surroundings, this acts grammatical its language. Compared discrete PRI set conventionally used train description, contains richer and more condensed structural information about train, helpful deinterleaving recognition. This article introduces semantic coding theory reveal reconstruct from train. We first define complexity divided into two parts: 1) encoding dictionary each element consisting several PRIs; 2) based on dictionary. then minimized by optimizing components in dictionary, patterns are finally obtained when minimization reached. effectiveness model reconstruction method verified simulation part.
