Autonomous Driving Integrated Sensing & Communications (ISAC)
ISACDrive converges automotive radar detection and vehicular V2X communications into a single radio frequency ecosystem. By employing shared 77 GHz waveforms, it tracks physical obstacle targets with sub-meter radar precision while simultaneously broadcasting multi-gigabit cooperative perception data.
ISACDrive Engine Core Zonal Architecture
Central Controller: ISACDrive Engine Core — Dual-Function 77 GHz Transceiver
Zonal Control Units & TSN Ring
- Cooperative Synthetic Aperture Radar (SAR) Fuser
- Unified Radar-V2X Waveform Modulator
- Joint Range-Doppler / Data Decoding DSP
- Zonal High-Bandwidth Autonomous Bus
- Mutual Interference Self-Cancellation Unit
Resolving the Severe Radio Spectrum Crunch in Autonomous Vehicle Sensor Suites
Autonomous vehicles pack dozens of independent 77 GHz radars and 5.9 GHz V2X antennas into bumpers and roof pillars, causing destructive mutual electromagnetic jamming and choking crowded urban crossroads. ISACDrive pioneers unified dual-functional waveforms: every radar ping transmitted down the highway doubles as a high-speed data burst to neighboring cars.
Core Engineering Areas
- Cooperative Bistatic Radar Imaging — Vehicle A transmits a high-power 77 GHz ISAC pulse; Vehicle B receives the scattered bounce, synthesizing a multi-perspective bistatic radar image that exposes hidden objects.
- Spectrum Sharing & Self-Interference — Deploying analog RF circulators and digital finite-impulse-response (FIR) cancellation filters to eliminate >110 dB of self-interference when transmitting and listening simultaneously.
- Distributed Vehicular SAR — Using the vehicle's forward travel velocity to synthesize a massive virtual antenna aperture, resolving centimeter-scale stationary road obstacles through fog and rain.
