General Atomics Aeronautical Systems (GA-ASI) is working with Leonardo to integrate the Leonardo Seaspray 7500E V2 radar into the centreline radar pod of its MQ-9B SeaGuardian remotely-piloted aircraft system (RPAS). The integration of this market-leading radar onto the SeaGuardian will enable persistent maritime ISR and is available to our international customer base.
GA-ASI’s MQ-9B is revolutionising the long-endurance RPAS market by providing 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 is well-suited to the SeaGuardian mission set, using 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 and the company has utilised operational feedback from these customers to expand and optimise 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 key discriminator 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.
