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.

IB-Lenhardt AG is one of the leading test houses for automotive radar certification and a great partner for improving the testing on the way towards autonomous driving.

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 are the functions of 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.

What does ADAS stand for?

Advanced Driver Assistance Systems (ADAS) are a suite of automotive radar sensor technologies designed to enhance a driver’s awareness and control of the vehicle. This can include features such as lane keeping assistance, forward collision warning, blind spot monitoring, adaptive cruise control, and automated parking. These systems can help reduce the number of collisions caused by human error.

What is the mmWave radar technology?

Millimeter wave radar (mmWave) is an active high-frequency radar system that uses electromagnetic waves in the millimeter wave range (30-300 GHz) with a wavelength of 1-10 mm to detect objects and measure their distance, speed, and angle. Unlike traditional radar systems based on long-wave radio waves, mmWave radar, with its much shorter range, can detect objects with greater accuracy and resolution. Additionally, mmWave radar is less affected by weather and other environmental conditions, making it ideal for applications that require reliable performance in challenging environments.
