Background

The modern battlefield is dynamic and highly complex. Technologies such as UAVs, stealth platforms, aspects of manned-unmanned teaming and sophisticated sensors represent current threats that could be encountered in a conflict scenario. Within a decade, Hypersonic Glide Vehicles (HGVs) and Hypersonic Cruise Missiles (HCMs) are likely to proliferate, and to counter these game-changing threats demands a radical advance in sensor and interceptor technology. Over the past 20 years, NATO near-peers have progressed rapidly their programs on symmetric and hybrid warfare. Threats such as highly integrated, networked radar and interceptors pose a challenge to defend against. The EM spectrum is increasingly being used as an instrument of power and therefore NATO needs to achieve superiority in this domain. The purpose of this SM is to distill the state-of-the-art in radar technology to counter and defend against the aforementioned threats. Combining aspects of Passive and Active sensing in various deployment constellations such as static and mobile ensures that redundancy and diversity can be exploited to greatly enhance NATO’s ISR capacity. The SM will provide the opportunity to explore the use of passive, LPI and LPR radar as well as utilizing multiband operation. Aspects of multi-use technology is expected to feature in the WS, such as utilizing a single radar architecture for multiple functions such as different radar modes as well as ECM and even communications functions.

Objectives

The main objective of the SM is the discussion of the future threats and the future sensor network able to detect all relevant threats in the modern battlefield. A continuous effort is seen in the development both of active and passive radars to detect and identify all moving objects both on ground, using e.g., GMTI technique and also in the air – drones, missiles, low visibility targets and many more. The main objective of the proposed SM is to discuss current trends in radar sensing and to form the recommendations and guidelines for future work and research.

Topics

• Coverage analyses for active and passive radar networks – ground and mobile, mission planning • Non cooperative target recognition (NCTR) including target imaging and identification by active and passive radars utilizing SAR and/or ISAR techniques • A performance analysis of DMPAR in co- and dislocated configuration for its deployment and assessment in military scenarios • Design and development tools for the deployment of deployable multiband passive/active radar (DMPAR) systems in military scenarios for having best performance of coverage and tracking • Signal processing techniques and ground clutter cancelation methods for active and passive radars (ground base and mobile) • Passive and active radars cooperation on moving platforms • Meeting the military requirements by active-passive radar network. • Radar network synchronization in GNSS denied environments • Update on the theme of Multi-Frequency RF Sensing (MFRFS)
