Automotive radar production testing

Automotive radar module and sensor production testing

Maximum automotive radar production yield and performance starts with precise measurements

Increasing demand for automotive radar sensors driven by the large number of radar modules in modern vehicles has led to double-digit growth in radar module production. Accurate and high-performance test equipment enables optimized margins and higher yield in production and this is key as sensor suppliers compete to offer ever-more demanding price-performance points.

Rohde & Schwarz trusted test and measurement solutions are used by almost all leading suppliers of automotive radar modules. Applying leading-edge test technology in production ensures compliance with performance specifications, maximizes yield and helps your competitiveness.

Your challenges in automotive radar production:

  • Implement a cost-efficient radar production test system with optimized test time and maximized yield
  • Development of calibration procedure in anechoic reference environment for automotive radar production
  • Small form-factor production tester even for large aperture sensors

Features of our radar test solutions:

  • Compact antenna test range (CATR) reflector with a quiet zone up to 30 cm for radar sensors with large antenna apertures.
  • High precision target simulators in 76 to 81 GHz range with configurable RCS and velocity
  • Highest accuracy power-sensors, field-proven in EOL production

Benefits of our automotive radar production test solutions:

  • Small form-factor compact antenna test range (CATR) chamber saves space in the factory
  • Better production yield of automotive radar sensors due to lower margin significantly reduces cost
  • Using the same test equipment in research and development and production reduces time-to-market
Minimum far-field distance
Compact antenna test range (CATR) reflector quiet zone up to 30 cm
