Architectural Layers & Waveform Pipelines

Layer 1: Sub-THz & RF Phased Array Front-End (GaN/InP PA / True-Time-Delay (TTD) / 140 GHz D-Band Active Arrays): Ultra-wideband signal generation, beam squint mitigation, and simultaneous transmission of communication and radar probing waves.
Layer 2: Dual-Functional Waveform & Baseband DSP (OTFS / Cyclic Prefix OFDM / Ambiguity Function Shaping / 2D-FFT): Orthogonal modulation in delay-Doppler domains, low peak-to-average power ratio coding, and deterministic clutter cancellation.
Layer 3: Joint Signal Processing & Point Cloud Extraction (Range-Doppler Matrix / MUSIC & ESPRIT DOA / CFAR Detection): High-resolution angle of arrival estimation, velocity extraction, ghost artifact elimination, and 4D spatial coordinate synthesis.
Layer 4: Multi-Static Mesh & 6G Sensing-as-a-Service (3GPP Rel-19 SBA / Sensing Function (SF) / NEF APIs / RIS Control): Cooperative radar data fusion across distributed cells, intelligent surface reflection control, and exposure of real-time environmental digital twins.

Sensing Telemetry & Benchmarks: <2.5 cm (Range Resolution) | ±0.05 m/s (Velocity Precision) | 0.1° (Angular Accuracy (DOA)) | 100 Hz (Sensing Update Rate)

Electromagnetic Coexistence & Precision Sensing in ISACRadio

Next-generation 6G communications merge high-throughput wireless data with ultra-accurate radar sensing into a single hardware and spectral envelope.
