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)

High-Speed IQ Ingestion & Time-Triggered Transport in ISACTelemetry

Transporting gigabytes of raw, uncompressed radar echo streams from distributed radio heads to centralized edge GPU clusters requires extreme-throughput telemetry backbones. ISACTelemetry formalizes zero-jitter, low-latency streaming infrastructure for 6G radar data.
