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.

Core Engineering Areas

Adaptive Spatial Null Steering Against Hostile RF Jamming — Real-time calculation of array receive weight vectors to place deep, sharp attenuation nulls directly toward incoming high-power jamming sources.
Fast Pseudo-Random Frequency Hopping in DFRC Waveforms — Hopping carrier frequencies and subcarrier permutations at over 100,000 hops per second to outpace fast follower jammers and spot frequency attacks.
Compressed Sensing and Sparse Waveform Recovery Under Barrage Jamming — Reconstructing clean radar range-Doppler maps and communication data from heavily punctured spectrum slices corrupted by wideband noise.
