In electronic warfare, deinterleaving is the task which sorts radar pulses in order to separate radar waveforms, without prior knowledge. This paper intends to evaluate two versions of a two-step deinterleaving method. It starts with a RF-PW clustering, then tries to merge some clusters by defining a distance related to their set of pulse times of arrival. After a parameter optimization, the method is evaluated with five metrics on a dataset consisting of simulated frequency-agile and PRI-modulated signals, and on a real data observation.
