AESA Radars (Active Electronically Scanned Array)

AESA radars represent the forefront of naval radar capabilities. By using hundreds of small transmitter-receiver modules, these radars can electronically steer beams at near-instant speeds without physically moving the antenna. Gallium Nitride (GaN) technology further boosts power efficiency and thermal stability, allowing AESA radars to detect, track, and prioritize multiple targets in real-time. Systems like HENSOLDT’s TRS-4D are now standard on many next-gen naval platforms, offering resilience against jamming and adaptability across mission profiles from air defense to surface surveillance.

Machine Learning Algorithms

Modern radars increasingly incorporate machine learning algorithms to enhance their environmental adaptability. These algorithms are trained on extensive datasets to distinguish between real threats and environmental clutter such as waves, birds, or weather phenomena. The result is reduced false alarm rates and improved signal clarity in high-noise littoral environments. This enhancement is especially critical in congested maritime zones where civilian vessels, military assets, and potential threats intermingle.

Radars and Multitarget Tracking

Compact radar systems are vital for deployment on UAVs and small vessels. Systems like the RDR-1700B, mounted on the MQ-9B SeaGuardian, provide full maritime situational awareness with low SWaP (Size, Weight, and Power) demands. These radars, when integrated with multitarget tracking capabilities, can handle simultaneous tracking of air, sea-surface, and near-shore contacts. Such agility ensures effective maritime patrol, anti-piracy, and SAR (Search and Rescue) operations even in expansive EEZs.
