They are intended for automotive use, operating in the 76-77 GHz band. The radars are integrated into a vehicle to enhance vehicle safety systems. They can be integrated as a standalone sensor or sensors, or as part of more complex system that also may include cameras, lidar, and other type of sensors to provide features like Automatic Cruise Control, Automatic Emergency Break, Free Space Detections and other Autonomous Driving functions. 1.2 Product Application Examples The product can be used, but is not limited to the following applications:
Autonomous drive systems Automatic braking systems Lane change warning Adaptive cruise control Collision prevention systems Automatic lane change systems Pedestrian and Bicycle collision prevention Etc. 1.3 Radiofrequency radiation exposure Information This equipment complies with FCC and IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance of 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Cet quipement est conforme aux limites d'exposition aux rayonnements IC tablies pour un environnement non contrl. Cet quipement doit tre install et utilis avec un minimum de 20 cm de distance entre la source de rayonnement et votre corps. Ce transmetteur ne doit pas etre place au meme endroit ou utilise simultanement avec un autre transmetteur ou antenne. User Manual for Product Model: 77V12CRN Page 3 of 8 2 Typical Installation The radar is typically installed in the positions of the vehicle depicted in Figure 1 often mounted behind a bumper or emblem. 1 4 0 Figure 1: Typical Installation Positions 3 Hardware Description The radar assembly consists of 2 PCB boards, one containing all the RF components, antennas and analog to digital converters and the other containing all that is necessary for signal processing and communications with the vehicle and power. The boards are assembled into a plastic housing that is laser welded together. The sensor has no serviceable parts and cant be opened without permanent damage.
