Automotive Radar SolutionsIB-Lenhardt AG has been supporting OEMs of vehicle radars in the worldwide type approval of their devices for many years. Our experts will also find customized solutions for you.
Vehicle Radar Sensors
Radar sensors significantly increase driving safety in modern vehicles. These sensors provide important support for drivers.
Equipped with ever higher technical intelligence, the increasing number of radar sensors of different frequency bands in Short-Range Radar (SRR, up to approx. 30 meters) serve to monitor blind spots and stop-and-go functionality, while Long-Range Radars (LRR, up to approx. 250 meters) provide automatic speed control and lane assistance. This makes such radars an indispensable component of intelligent vehicles as a prerequisite for the planned future of autonomous driving.
With the establishment of an accredited laboratory area for electrical safety, EMC and radio, IBL-Lab GmbH (a 100% subsidiary of IB-Lenhardt AG) lays the foundation for the necessary metrological proof of conformity through test reports, which in turn ideally support the customer's type approval project at 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.

All you need to know
- How does a radar work?
Radar means radio detection and ranging. A radar detects objects via electromagnetic or radio waves. The radar can not only measure the distance, but also the angle and the relative speed of moving objects to the target object. The electromagnetic waves generated by the radar transmitter travel at the speed of light to the target object, where they are reflected. The radar receiver—usually the transmitter and receiver antennas are located on the same radar chip—processes and analyzes the signal to determine, depending on the type of radar, the distance, speed and position of the object.
- What is radar in a car?
In cars there are used two different types of radars: short range radar (SRR) and long range radar (LRR). They are an indispensable component of the autonomous driving assistance system (ADAS). SRR serves for blind spot detection and stop-and-go functionality, LRR for automatic speed adaptation and lane assistance systems. Automotive radar is one of the several sensor systems for collision avoidance, pedestrian and cyclist detection, and complements vision-based camera-sensing systems.
- Where is radar located in a car?
For design reasons, the radar sensor is usually integrated into the vehicle behind covers such as bumpers or radoms. For proper functionality, it is important that the sensors are mounted in the exact radar-permeable location intended for this purpose. Only these areas are optimized for optimum radiation of the radar signals.
- Can radar see through cars?
With a radar it is possible to radiate through non-conductive materials, such as plastic, rubber, cardboard, glass, etc., because the radar waves only partially reflect these dielectric materials. But radars are not able to see through metals, consequently also not through cars. The electromagnetic waves that are emitted by a radar are reflected by objects and then received and evaluated. This reflection would not be possible if radar sensors could see through cars. Therefore the radars are exactly located in radar-permeable positions.
- What cars use radar?
Cars that support autonomous driving technology use radar functions. These include companies such as BMW, Volkswagen and Mercedes Benz. Tesla uses for its semi-autonomous cars radar sensors exclusively.
- Is a radar a sensor?
A radar is not a sensor but a designation for various detecting and locating methods and devices using bundled electromagnetic waves in the radio frequency range. The sensor is located in a device that uses radar. They convert microwave echo signals into electrical signals using a wireless sensing technology.
