IB-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.

Overview

Vehicle Radar Sensors

Radar sensors in modern vehicles contribute significantly to increasing driving safety and provide valuable support to the driver. IBL-Lab GmbH, a wholly owned subsidiary of IB-Lenhardt AG, lays the foundation for the required metrological proof of conformity of the various radar sensors with the DAkkS-accredited laboratory for electrical safety, EMC testing and regulatory radio testing. A first important step for your type approval.

In addition, IBL-Lab GmbH has partnered with Rohde & Schwarz to build a radar laboratory that exceeds current regulatory requirements for radar sensor performance and quality indicators, such as noise immunity, multi-target capability, accurate sensor positioning, and calibration of the sensor's emitted transmission power.

With the progress in autonomous driving, the number of radar sensors needed in a vehicle is increasing:

  • SRR - short-range radar, up to about 30 meters: At close range, radar sensors are used to monitor blind spots and support stop-and-go functionality,

  • MRR - Mid-Range Radar, up to approx. 150 meters: Radar sensors with cross-traffic alert and lane change assistance,

  • LRR - Long-Range Radar, up to approx. 250 meters: Radar sensors for automatic speed control and lane change assistance.

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 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.
