Deinterleaving with limited input parameters

The interleaving is an essential part of the radar warning receiver (RWR) decision making process. Received signals are processed to classify the source which RWR observes and to determine the level of threat. Proposed de-interleaving algorithm is based on the presumption that only limited set of input parameters is available. The algorithm is based on the combination of pulse-width selectors, pulse-repetition-interval selectors and final group pulse detector. De-interleaving algorithm has been implemented into the FPGA circuit.
