Architectural Layers & Waveform Pipelines

Livello 1: Forma d onda a doppia funzione e banda base (OTFS / OFDM-Radar / Fractional Fourier Transform / Ambiguity Function): Modulazione OTFS e sintesi frazionaria di chirp ottenendo interferenza inter-portante zero sotto forti dispersioni Doppler.
Livello 2: Massive MIMO e frontend di beamforming (140 GHz D-Band / True-Time-Delay (TTD) / Hybrid Analog-Digital Beamforming): Matrici a controllo di fase attive Sub-THz con mitigazione del beam-squint, fasci di dati di comunicazione e lobi radar simultanei.
Livello 3: Elaborazione del segnale radar e nuvola di punti 4D (2D-FFT Range-Doppler / MUSIC AoA / CFAR Detection / Micro-Doppler Extraction): Risoluzione sub-decimetrica di portata e velocità, rilevamento CFAR e classificazione micro-Doppler di andatura e pale di droni.
Livello 4: Orchestrazione del rilevamento di rete e 3GPP Rel-19 (3GPP Rel-19 ISAC Core / Sensing Function (SF) / Reconfigurable Intelligent Surfaces (RIS)): Reti radar collaborative cell-free, allocazione dinamica delle risorse tempo-frequenza tra SLA di comunicazione e tempo di scansione radar.

Sensing Telemetry & Benchmarks: <5 cm (Risoluzione di portata) | 0.1 m/s (Precisione di velocità) | <10 ms (Latenza frame radar) | 3GPP Rel-19 (Standard globale)

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.
