Fraunhofer Institute for Applied Solid State PhysicsThe frequency range of 75 –110 GHz (W-band) is ideal for radars to detect small objects from a distance, even if visibility is restricted. Due to the production costs and device size, radar systems have only been used to a limited extent so far. A research group has now developed a compact and modular W-band radar for diverse and flexible use.
Radar for sensing and material testing
The W-band radar module measures only 78 x 42 x 28 mm3.
Features
- High range of coverage and accuracy
- Phase-locked loop for chirp generation with frequency multiplication
- GaAs-based integrated circuits on cost-effective polymer substrate
- Broadband antenna with dielectric lens
- Integrated signal processing and object analysis
The W-band radar provides reliable monitoring of container ports even in fog.
Applications
- Industrial sensors: precise distance measurements under limited visibility conditions
- Logistics: monitoring of container ports
- Medical technology: intelligent medical devices
- Air safety: landing aid for helicopters
- Transportation: railway technology
