SRR5-B / User Manual ADC GmbH 1. Purpose In this document an operational description of Continental´s 77 GHz Advanced Radar Sensor SRR5-B is given. Sufficient information is provided to understand the operation principle, the set up and the tuning of the radar sensor. page Copyright © by Continental 2019 All rights reserved 2/5

SRR5-B / User Manual ADC GmbH 2. General information The SRR5-B sensor measures independently the distance and velocity (Doppler's principle) to objects without reflector in one measuring cycle on the basis of FMCW (Frequency Modulated Continuous Wave) with very fast ramps. A special feature of the device is the simultaneous measurement of large distances up to 99 meters, relative velocities between ±300 km/h and the angle relation between two objects. The sensor is mounted in the front or rear corner of the car behind the bumper, as illustrated in Figure 1. Figure 1: Illustration of the mounting position of the SRR5-B The sensor performs in alternation a Short Range (SR) Scan cycle and a Far Range (FR) Scan cycle. The Short Range Scan covers distances up to 12.6 meters and angles of ±90 degrees in front of the sensor. The Far Range Scan covers distances up to 99 meters with angles of ±90 degrees. The sensor allows a detection of objects in the given Field of View (FoV) and evaluates the current constellation under consideration of all detected objects and among others the following information: ➢ Vehicle Dynamics Data (e.g. Velocity, Acceleration, Yaw Rate of the host vehicle) which is transmitted to the sensor from the car via the vehicle bus The sensor SRR5-B is designed for comfort/safety applications in passenger cars and trucks like Blind Spot Detection, Rear Cross Traffic Alert (with braking), Lane Change Assist, Trailer Detection In dependence of the overall information the sensor outputs specific messages, which may then be used by other vehicle components (braking system, power train, door modules etc.). page Copyright © by Continental 2019 All rights reserved 3/5

SRR5-B / User Manual ADC GmbH 3. SRR5-B Sensor Component Description The SRR5-B sensor consists of the following components: ➢ Plastic housing with sensor Controller Area Network (CAN) connector ➢ Radio Frequency (RF) Printed Wiring Board (PCB) including the antenna which is plugged into the housing ➢ Low Frequency (LF) PWB incl. Board-to-Board (B2B) Connector (connector between RF and LF unit) ➢ A plastic molded radome through which the radar beams are emitted. page Copyright © by Continental 2019 All rights reserved 4/5

SRR5-B / User Manual ADC GmbH 4. SRR5-B Sensor Software Operation Only one operational mode exists where the sensor measures continuously with pulse frequency modulation (FM). The sensor operates in this mode over its life time in the vehicle, being powered by the vehicle power supply. page Copyright © by Continental 2019 All rights reserved 5/5
