Passive radar has specific properties making it attractive for military purposes. These are among others silent operation and anti-stealth capability. Their performance capabilities have been studied extensively and passive radar technology has reached a state of maturity, which makes it a candidate for concrete military applications. At the present moment, several operating units of military ground based passive radars have been constructed and many more are in R&D stage. In addition to ground based stationary installations of passive radar approaches have been undertaken to address passive radar on airborne and maritime platforms.


n continuation of the research on passive radar technology for moving platforms the benefits and challenges of passive radar for military applications on moving ground based, maritime and airborne platforms shall be studied in a new SET-activity. The work will have strong relations with the LTCR’s as follows: LTCR Priority 10 - Counter Low Signature Airborne Targets; COP, active and passive sensors, target RCS vs bistatic observation angle, LTCR Priority 12 - Counter Rocket, Artillery and Mortar: advanced radars LTCR Priority 13 - Counter Threat to Low Altitude Air Vehicles; sensors to detect threat, LTCR Priority 25 - Intelligence Surveillance & Reconnaissance (ISR) Collection Capability: Active and passive sensors Moreover there is connection between the topics mentioned above and CNAD DAT ITEM 1: Large Aircraft Survivability and DAT ITEM 3: Protection of Helicopters from Rocket-Propelled Grenades (RPG) As far as relations with UK Taxonomy are concerned one can point out on topics as follows: A09.02 – DSP Technology, A09.08 - Information and Data Fusion Technology B06.02 – RF Sensors B10.09 – Non-Co-operative Target Recognition. C01.03 - Platform and System Concept Studies C06.09 - Counter Stealth R02.L02 - Counter Low Signature Airborne Targets


The focus of this study will be on the specific phenomena related to the changing scenario of environment and interference for moving platforms, the signal processing aspects with respect to platform motion as well as on system aspects and conceptual considerations for maritime and airborne military vehicles. The study will be a continuation of the work of SET 186 “Airborne Passive Radars and their Applications APRA” and also works undertaken in the frame of the group SET-195 “DMPAR short term solution” The research will identify basic phenomena including platform motion models as well as signal and clutter models, identify technological challenges including hardware and signal processing development, identify end user requirements and address operational usefulness. The output of this study will be a final report . - A performance analysis of the moving sensors - Signal processing and clutter cancelation - Data fusion, target localization and tracking - User requirements - Platform motion compensation - Reference signal reconstruction - Direct signal suppression - Multi-band processing
