In contested airspace where threats evolve faster than traditional systems adapt, RAT 31DL L-band 3D surveillance radar delivers high-precision detection through NATO-proven advanced AESA technology. Capable of detecting airborne targets beyond 500 km, its phased-array architecture enables rapid, high-resolution tracking, while the system’s ultra-low sidelobe antennas and adaptive ECM resistance ensure continued performance in the face of jamming and Anti-Radiation Missiles. Designed for resilience and adaptability, RAT 31DL integrates seamlessly with defence networks and operates with solid-state reliability 24/7, maintaining critical responsiveness across the most demanding operational environments.
Advanced AESA Technology for Precision 3D Long Range Surveillance
RAT 31DL utilises L-band solid-state AESA technology to deliver precise 3D Long Rnge airspace surveillance. Its phased-array antenna produces multiple, independently steerable pencil beams for rapid sector scanning and fine-grain target tracking at ranges exceeding 500 km. Monopulse processing ensures precise altitude determination, while frequency agility and seamless IFF integration enhance mission adaptability. A software-upgradable architecture allows for continuous capability updates, keeping RAT 31DL constantly aligned with evolving operational demands.
Resilience in Contested Environments
Engineered for high-threat environments, RAT 31DL incorporates ultra-low sidelobe antennas and ECM-monitoring receivers to withstand jamming attempts and advanced electronic warfare. Reduced peak power and agile frequency hopping protect against Anti-Radiation Missiles and sophisticated ECM tactics. Jam-strobe reporting and Dynamic MTI filtering, synchronised with real-time terrain mapping, suppress interference from clutter such as ground returns, sea, precipitation, chaff and atmospheric conditions. Proven in global deployments, RAT 31DL consistently delivers robust ECCM performance in complex electromagnetic scenarios.
Modular Design & Operational Adaptability
RAT 31DL’s modular architecture enables rapid assembly, disassembly, and relocation across diverse mission profiles. It deploys flexibly on towers, ground stations, or within radome-protected/unprotected platforms, integrating via local or remote management interfaces. Built for 24/7 operation in extreme environments, the radar features graceful degradation to maintain functionality during component stress. Fully interoperable with contemporary defence networks, RAT 31DL allows armed forces to achieve uninterrupted long-range coverage, faster threat response, and comprehensive airspace awareness in any operational theatre.
