Room-002 (Hybrid)\ n\nAbstract\n\nSpaceborne Synthetic Aperture Radar (SAR) is increasingly a ffected by radio frequency interference (RFI) due to growing spectrum cong estion and the proliferation of emitters across shared and adjacent bands. Although substantial progress has been made in modelling\, detecting\, an d mitigating RFI on the ground after data downlink\, this conventional wor kflow can be inefficient for time-critical and resource-constrained missio ns\, while also limiting opportunities for adaptive onboard sensing.\n\nTh is talk presents a systems-level perspective on RFI resilience in spacebor ne SAR. It begins with a concise overview of RFI phenomenology in SAR\, in cluding modelling\, detection\, and mitigation in both raw and focused dat a. It then examines the practical limitations of ground-based post-process ing and contrasts them with the potential benefits of onboard detection an d mitigation\, particularly for early disaster monitoring\, rapid vessel d etection\, improved mission autonomy\, and reduced transmission of corrupt ed or low-value data. The talk will discuss candidate onboard processing p athways\, including raw-data-domain processing\, FPGA-accelerated architec tures\, and edge-AI approaches\, together with system constraints such as power\, latency\, hardware complexity\, and information leakage risks\, in cluding side-channel considerations. Finally\, it will highlight emerging directions such as neuromorphic sensing and other unconventional computing paradigms as possible long-term enablers of intelligent onboard SAR paylo ads.\n\nBio\n\nDr Nermine Hendy (Senior Member\, IEEE) is a Research Fello w at RMIT University\, Australia.
