One technology, many fields of application
Our solutions open up versatile, high-performance fields of application – especially where high resolution, compactness and robustness are required:
- Autonomous traffic, autonomous logistics: high angular resolution, small antenna size, weather-independent detection - even in rain/fog/night. Ideal for 360° environment detection.
- In-line production, quality control and material characterisation: non-contact, through dust, plastic or housing, maintenance-free and robust against interference - perfect for harsh industrial environments.
- Security and surveillance technology: Through-wall detection (partial), high resolution with compact design, low susceptibility to interference - more reliable than conventional optical systems.
- Medical applications: Hygienic, inconspicuous, contactless - ideal for sensitive or hard-to-reach patient groups.
- Precise position and distance determination without GPS
- Agriculture and environmental monitoring: vegetation monitoring, soil structure and moisture analysis.
