Integrierte Sensorik & Kommunikation (ISAC) für autonomes Fahren
ISACDrive verschmilzt Kfz-Radardetektion und V2X-Kommunikation in einem einzigen HF-Ökosystem. Über gemeinsame 77-GHz-Signale werden Hindernisse zentimetergenau erfasst und Gigabit-Wahrnehmungsdaten geteilt.
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
Lösung des akuten Funkspektrum-Engpasses in Sensorsätzen autonomer Fahrzeuge
Autonome Fahrzeuge packen Dutzende Radare und V2X-Antennen in Stoßfänger, was verheerende Funkstörungen an Kreuzungen auslöst. ISACDrive nutzt duale Wellenformen: Jeder ausgesendete Radarimpuls dient gleichzeitig als High-Speed-Datenpaket für Nachbarfahrzeuge.
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.
