Guardian

Guardian is an airborne X-band multi-mode SAR radar developed by MetaSensing for defence ISR applications. The system weighs 35 kg and integrates embedded heterogeneous computing (FPGA, GPU, CPU) for real-time on-board processing. Operational modes include spotlight SAR (0.3 m resolution), stripmap SAR (3 m resolution), Ground Moving Target Indication (GMTI, detection range over 200 km), Maritime Moving Target Indication (MMTI), and Inverse SAR (ISAR) for target classification. The sensor is designed for integration on tactical UAV and TUAS platforms and provides all-weather, day-night 360-degree azimuth coverage. Multiple units have been delivered since 2022 for border and maritime surveillance operations in the Mediterranean, Middle East, and Asia regions.^[1][2][3] Public MetaSensing materials frame Guardian for defence ISR; no documented EO Earth-science application has been identified in available sources.
