From the link:
The ELK-7065 is a state-of-the-art HF COMINT system suitable for the harsh electromagnetic environment characterizing the HF band. The system tags and identifies signals characteristics in a multi-dimensional domain, composed of signal identifiers such as power, center frequency, modulation, geo-location, polarization and more. These techniques enable swift labeling of the received signals, identification and reliable Electronic Order of Battle (EOB) generation. The unique front-end technology allows installation on board compact airborne platforms, such as mission aircraft of all sizes and UAVs.
