Precise techniques to detect superimposed radar pulses on ESM systems

Abstract

The latest works on the radar pulse de-interleaving in electronic support measures (ESM) systems have not completely solved the missing pulses problem yet. The authors present a pulse detection algorithm that aims at, if not eliminating it, diminishing the rate of pulses not detected because of the fact of being superimposed in other ones. Experiments set up on an ESM system based on software-defined radio (SDR) showed that the algorithm detection rate was near a hundred per cent and the false alarm rate was near zero when pulse amplitudes were > 3.9 mV in the SDR input. This work is suggested for the areas of digital and radar signal processing and electronic warfare.
