Leonardo Seaspray AESA Maritime Radar for MQ-9B SeaGuardian

Leonardo's Seaspray 7500E V2 radar, to be integrated on the MQ-9B SeaGuardian, uses Active Electronically Scanned Array (AESA) technology to detect, track and classify hundreds of maritime contacts. Arun Sivasankaran - : Jan 18, 2021 - : 8:46 pm

General Atomics Aeronautical Systems, Inc. (GA-ASI) and Leonardo will integrate the Leonardo Seaspray 7500E V2 radar into the centerline radar pod of the MQ-9B SeaGuardian remotely-piloted aircraft system (RPAS).

The integration of the radar onto the SeaGuardian will enable persistent maritime ISR. GA-ASI’s MQ-9B provides all-weather capability and compliance with STANAG-4671 (NATO airworthiness standard for Unmanned Aircraft Systems). These features, along with an operationally proven collision-avoidance radar, enables flexible operations in civil airspace.

SeaGuardian has a multi-mode maritime surface-search radar with Inverse Synthetic Aperture Radar (ISAR) imaging mode, an Automatic Identification System (AIS) receiver, and a High-Definition – Full-Motion Video sensor equipped with optical and infrared cameras. This sensor suite, augmented by automatic track correlation and anomaly-detection algorithms, enables real-time detection and identification of surface vessels over thousands of square nautical miles.

The Seaspray 7500E V2 radar uses Active Electronically Scanned Array (AESA) technology to detect, track and classify hundreds of maritime contacts. The integration will also include an Open Mission Systems (OMS) approach, which enables the SeaGuardian and its sensor suite to offer operational and sustainment flexibility to end users.

Numerous countries use Leonardo Seaspray E-scan radars. The company has utilized operational feedback from its customers to expand and optimize the radar’s suite of advanced modes. These include Leonardo’s patented small target detection capability, allowing it to spot extremely difficult targets such as submarine periscopes and shipwrecked individuals at long range, even in very stormy seas. A unique feature of Leonardo’s E-scan radars is their high reliability and fault tolerance that allows effective operation throughout a mission even if a number of individual radar modules fail.

Earlier this year GA-ASI announced the completion of initial integration work of Leonardo’s SAGE electronic surveillance unit onto the SeaGuardian, equipping the aircraft with the ability to gather intelligence information on maritime and land-based radar emitters over a wide area. Both Seaspray and SAGE will be off-the-shelf sensor options for the SeaGuardian.
