Automotive radar sensors are usually mounted behind bumpers or radomes and their material quality has a significant influence on the performance of the radar system and the function it supports, for example ADAS. When selecting radome and bumper materials, care must be taken to ensure minimized and consistent RF penetrability to avoid angular errors, signal distortions and attenuation. At the same time, suppliers face the challenge to meet demanding specifications defined by vehicle manufacturers in a cost and time efficient way. This webinar will explain how microwave imaging technology can be utilized to provide accurate, 2-dimentional characterisation of radome and bumper quality, accelerate the design cycle and facilitate seamless transition from development in the lab to high-volume production.
