Radar sensors significantly increase driving safety in modern vehicles. These sensors provide important support for drivers.

Equipped with a mounting amount of higher technical intelligence, the increasing number of radar sensors of varying frequency bands in the short range (Short-Range Radar, up to circa 30 meters/yards) serv the purposes of blind spot monitoring and stop-and-go functionality, while Long Range Radars (LRR, up to circa 250 m/yd) provide for automatic speed control and lane assistance. Thus, such radars are an indispensible part of intelligent vehicles as prerequisite for the planned future of autonomous driving.

For many years, IB-Lenhardt AG has been supporting OEMs of vehicle radars with the world-wide type approval of their devices, accumulating thorough knowledge of regulatory and quality requirements of vehicle radars. By establishment an accredited lab segment for electric safety, EMC and radio, IBL-Lab GmbH (a 100% subsidiary of IB-Lenhardt AG) lay the foundation for the necessary metrological evidence of compliance through test reports, which in turn ideally supports the client's type approval project with IB-Lenhardt AG.

Furthermore, IBL-Lab GmbH together with Rohde & Schwarz have established a radar lab which surpasses current regulatory requirements in terms of radar sensors' performance and quality indicators, such as resilience against interference, multi-target capability and exact positioning of the sensor and calibration of the sensor's emitted transfer power.
