Paper Abstract

In the naval electronic environment, pulses emitted by radars are collected by electronic support measures receivers. The aim is to gather these pulses in such way that one cluster corresponds to one radar despite the waveform parameters agility. To achieve it, this paper describes a pulse train deinterleaving process using a multi-hypotheses architecture. A hypothesis tree, built from pulse measurements, represents all the possibilities to associate pulses to emitters, according to one hypothesis of pulses association. Different processes are used to find the valid hypothesis that correspond to emitters. These processes have two aims: avoiding the combinatorial explosion of the number of hypotheses, and to lead to the solution tree: one branch corresponds to one effective emitter. Radars waveforms with agile parameters are considered. A new process has to be added to take into account missing pulses.
