FUNCTION OVERVIEW

CTLRR-410 is a 77GHz long range millimeter wave radar independently developed by ChengTech Technology. The domestic SoC scheme integrating a new generation of RFCMOS is adopted, and the antenna array is designed with wide and narrow beam scanning to improve the angle resolution while taking into account the detection range, which can accurately measure the distance, speed, angle and other information of the target vehicle within 220m in front of the vehicle.

ADVANTAGE

1. Support the function of pitch height measurement, and be able to identify high-altitude and ground targets;

2. MIMO+virtual aperture+DML super-resolution angle measurement scheme is adopted in the design to greatly improve the angle measurement resolution;

3. Adopt the SoC scheme of domestic RFCMOS technology, effectively reduce radar power consumption and have great advantages in cost;

4. Support ISO26262 functional safety level up to ASIL-B;

5. Support AutoSAR software architecture;

6. Support automatic calibration/anti-interference/occlusion detection;

7. Meet the performance requirements and detection methods of GB/T 33577-2017 intelligent transport system vehicle forward collision warning system;

8. Meet the performance requirements and test methods of GB/T 39901-2021 Automatic Emergency Braking System (AEBS) for Passenger Cars;

9. Meet the performance requirements and test methods of Automatic Emergency Braking System (AEBS) for commercial vehicles (GB/T 38186-2019);

10. Meet the performance requirements and test procedures of JT/T 883-2014 automatic emergency braking system for commercial vehicles;

11. Meet the performance requirements and test procedures of JT/T 1242-2019 automatic emergency braking system for commercial vehicles.
