Specific Emitter Identification: Analysis on real radar signal data

This paper focuses on the specific emitter identification (SEI) technique applied to electronic support measure (ESM) systems. The main idea is to analyze the radar pulses and characterize those by extracting features that should be different for each radar. In the paper, feature extraction algorithms are used to characterize the radar pulses: a measurement campaign has been conducted to acquire real radar pulses from different radar modes and radar signals. The applicability of the feature extraction procedure has been analyzed for different case studies to obtain a complete picture of the results achievable with the different radar signals.
