Robust pulse repetition interval (PRI) classification scheme under complex multi emitter scenario

The research is focused on the Pulse Repetition Interval (PRI) Classification of radar data received by an Electronic Intelligence (ELINT) Platform. Pre-sorted on the basis of basic parameters of Pulse Descriptor Words (PDWs) and de-interleaved, the data is classified with a technique presented in this research, to one of the known six types of PRIs (e.g. Constant, Staggered, Jittered, Sliding, Dwell & Switch and Sinusoidal). The proposed technique is focused on ease of implementation. Robustness of the algorithm is also tested against impurities like Missing pulses, Spurious pulses and Incidental jitter. PRI Classification rate is determined on the basis of synthetic data generated in MATLAB.
