Architectural Layers & Waveform Pipelines

Layer 1: Dual-Functional Waveform & Baseband (OTFS / OFDM-Radar / Fractional Fourier Transform / Ambiguity Function): Orthogonal Time Frequency Space (OTFS) modulation and fractional chirp synthesis achieving zero inter-carrier interference under severe Doppler spreads.
Layer 2: Massive MIMO & Beamforming Frontends (140 GHz D-Band / True-Time-Delay (TTD) / Hybrid Analog-Digital Beamforming): Sub-THz active phased array architectures with true-time-delay beam-squint mitigation, simultaneous communication data beams and pencil radar tracking lobes.
Layer 3: Radar Signal Processing & 4D Point Cloud (2D-FFT Range-Doppler / MUSIC AoA / CFAR Detection / Micro-Doppler Extraction): Sub-decimeter range and velocity resolution, constant false-alarm rate (CFAR) detection, and micro-Doppler biomechanical gait and drone propeller classification.
Layer 4: Network Sensing Orchestration & 3GPP Rel-19 (3GPP Rel-19 ISAC Core / Sensing Function (SF) / Reconfigurable Intelligent Surfaces (RIS)): Cell-free collaborative radar networks, dynamic time-frequency resource allocation balancing communication SLA against radar revisit time.

Sensing Telemetry & Benchmarks: <5 cm (Range Resolution) | 0.1 m/s (Velocity Precision) | <10 ms (Radar Frame Latency) | 3GPP Rel-19 (Global Standard)

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.
