Continental’s 3rd-generation short-range radar sensor: a simplified design improves cost-effectiveness
The Continental SRR3-B is designed for automotive applications like blind-spot detection, lane-change assist, rear cross-traffic alert, rear pre-crash, safe exit, collision mitigation, distance warning /monitoring, and more. The SRR3-B is based on 24 GHz technology and contains a planar antenna. The sensor has a field of view of ±75° in azimuth and a maximum range of more than 90m.
The system integrates two electronic boards. The MCU board includes a microcontroller from NXP Semiconductor. The RF board is manufactured with a symmetric structure using hybrid PTFE/FR4 substrate and is equipped with planar antennas. 24GHz SiGe monolithic microwave integrated circuits (MMIC) from Infineon are used as high-frequency transmitter and receiver.With this 3rd-generation short-range radar, Continental has reduced by 25% the total number of components used and significantly decreased the manufacturing cost, compared to the previous generation (SRR2).Based on a complete teardown analysis of the Continental SRR3-B, this report provides the radar sensor’s BOM and manufacturing cost.
