Background: During the work carried out within SET-258 RTG, the data fusion from the active radar and passive radars utilizing traditional ground-based illuminators of opportunity (IoO), such as FM, DAB and DVB-T has been performed. The use of novel IoOs, introduced recently in commercial service, has not been addressed and could make a significant added value for modern multiband active/passive radar (MPAR) operation. SET-258 RTG identified that in future networked PCL radars it is a strong need to study novel wideband illuminators, such as 5G/6G base station transmitters, and their usage in modern security and military applications. Additionally, RTG identified that the main drawback of the current ground-based IoOs for PCL is limited coverage. The preliminary study shows, that using satellite-based illumination, can give in future global coverage for passive radar operation. Instead, the well-known GNSS and DVB-S IoOs, the recently launching dense network of the STARLINK satellite constellation seems to be a perfect candidate in future for passive radar operation. Additionally, the PCL systems utilizing ground-based IoOs coverage is often limited by the lack of possibility to get the over-the-horizon reference from far IoOs. This drawback can be solved by equipping the PCL system with the additional air-lifted reference receiver, which will be part of the passive system. Such a configuration will allow to significantly increase PCL coverage. An additional point is the low RCS and low altitude flying targets detection using passive and active radar technology. The current state of the art shows potential for such detection at distances of several kilometres, but still, classification is a huge advantage to properly classify the man-built targets. All mentioned here techniques have been identified in SET-258 RTG as a new frontier in modern passive radars, which required further deep analysis and which can provide a significant coverage increase of future netted PCL system and give also potential for the global coverage of the passive radars, which can also support future multiband active/passive radar operations. Additionally, those frontiers can be extended by studying within the planned activity the ECCM properties for PCL systems in the modern battlefield. Thus, a three years RTG activity is required to study and validate. For these purposes, the SET-320 RTG on new frontiers in modern passive radars has been proposed. It will be in the interest of the NATO nations in the future to increase the coverage of modern active/passive radars.
Objectives: The objective of the RTG is to perform theoretical study and experiments as well as develop new signal processing algorithms, and data fusion algorithms to demonstrate the benefits of using novel ground-based and space-borne IOs for modern passive radars, as well as utilizing air-lifted reference for ground-based PCL to increase the passive radar coverage and also potential to detect and track low altitude and low RCS airborne targets. Additionally, the group aims to organize and perform international joint trials. The RTG aims to generate research output through publications, conference special sessions and journal special issues.
Topics: The research of the proposed RTG will identify basic phenomena relevant for finding the new frontiers in modern passive radars, including new IOs and netted ground-based and air-lifted sensors configuration, in order to provide answers on how this technology can be supported in the future modern battlefield.
