Automotive radar production testing

High radar production yield and maximum 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 minimized 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 developers of automotive radar. Applying leading-edge test technology also in production reduces risks and helps your competitiveness.

Your challenges

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

Features of our automotive radar production testing solutions

  • Future-proof Compact Antenna Test Range anechoic chamber with a quiet zone of up to 30 cm to develop calibration procedure even for imaging radar with large antenna apertures.
  • High precision target simulator with 4 GHz bandwidth within 76 to 81 GHz range and up to 4 radar objects with configurable RCS and velocity
  • Highest precision power-sensors, field-proven in production
  • Cost-efficient mid-range spectrum analyzers or oscilloscopes for monitoring compliance with spectral emission requirements
Minimum far-field distance
Benefit of using a CART compared with direct field testing
Open Lightbox

Benefits of our solutions

  • Small form-factor Compact Antenna Test Range chamber saves space in the lab and factory
  • Better production yield due to lower margin significantly reduces cost
  • Efficient compliance monitoring reduces liability risks
  • Consistent test setup in R&D and production reduces time-to-market
