Adaptive Jamming Nulling & Resilient Waveforms in ISACShield

Civil infrastructure, autonomous vehicle fleets, and tactical communications face escalating threats from intentional RF jamming, electronic warfare (EW) barrage signals, and malicious sweeping interferers. ISACShield deploys high-speed adaptive spatial filtering, ultra-fast frequency hopping, and compressed-sensing sparse recovery to maintain radar tracking and gigabit communications amidst severe spectral denial.
