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)

ISO 26262 ASIL D Radar Supervision & Emergency Braking in ISACSafe

Autonomous mobility and industrial robotics cannot compromise on safety integrity. When radar sensing and wireless telemetry share the same RF hardware and baseband processing pipelines, hardware faults or software latency could lead to catastrophic collisions. ISACSafe establishes deterministic, fail-operational supervisory channels with sub-millisecond automated emergency braking interlocks.

Core Engineering Areas

ISO 26262 ASIL D Lockstep Baseband Architecture and Hardware Supervision — Hardware architectures implementing redundant dual-core lockstep processing and online diagnostic coverage exceeding 99% for safety-critical ISAC systems.
Sub-Millisecond Radar-Actuated Emergency Braking (AEB) Interlock — Direct hardware coupling between dual-function radar echo detection pipelines and electro-mechanical brake-by-wire actuators for zero-jitter safety reaction.
Fail-Operational Antenna Array Beamforming and Graceful Degradation — Preserving radar angular resolution and telemetry throughput during partial hardware failure across multi-element active phased array transceivers.
