The performance of the radar sensor and the safety-critical system it supports for automotive radars is influenced by the material’s RF transmission and reflection properties, which are often installed behind bumpers or radomes.
Autonomous vehicles need sensors that can identify adjacent objects. These include radar sensors, but also cameras and lidar sensors are included. Every year, millions of vehicle radars are made.
They come as standard in expensive cars. Today, the primary purposes of car radar sensors are to improve driving comfort and reduce collisions. Automotive radars are protected by a radar dome (radome) made of a material transparent to RF waves for aesthetic rather than functional reasons.
Although the grille emblem is frequently employed for this, radars can also be effectively concealed by using plastic bumpers. Particularly for operating in the mmWave band, RF performance issues can be brought on by the three-dimensional shape of brand emblems with locally changing material thickness.
Metallic paint is frequently used to coat bumpers, which dampens high frequencies. Validating radome material qualities and analysing their impact on radar signals are consequently crucial to ensuring radar dependability.
The Global Automotive radome testers market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Automotive Radome Quality Tester R&S QAR50,from conception to end-of-line testing, ensuring the quality of vehicle bumpers and radomes.
For precise end-of-line testing of car radomes and bumpers in the automotive radar frequency band, the R&S QAR50 is the best tool (EOL). It has enough room for large bumpers to fit without difficulty, and it also has spatially resolved measures to assess the uniformity of design emblems.
The company’s cutting-edge hardware design enables the industry’s quickest measurement turnaround times, while the modular software design enables customization to meet your unique needs. With speed and accuracy and at a very competitive price, the R&S QAR50 performs radome and bumper testing.
Frequency response and precise measurements of transmission loss and reflection in the automobile radar bands (72 GHz – 82 GHz).With a single measurement, spatially resolved transmission phase and high resolution reflection image are obtained. A four second ultra-short cycle time enables excellent production throughput.
Accuracy similar to a VNA owing to compliance verification set up with plates to verify transmission loss and reflection. Internal self-calibration, no mounting or other equipment necessary
