TI公司的TIDA-020004是汽车RFCMOS 77GHz雷达模块参考设计,为用户提供了测试76GHz到81GHz雷达传感器模块的解决方案.板上电源能汽车输入电池转换成雷达模拟前端(AFE),处理器,带灵活数据速率的控制器局域网(CAN-FD)收发器所需的电源.经过处理后,目标数据在包括CAN-FD物理层(PHY)上发送.参考设计集成了DSP和MCU,VIN电压宽达36V OFF电池电压,容差高达42V,诊断和监测功能可用于ASIL B应用.PCB尺寸仅为50 mm×71 mm,电源也是优化的,具有小尺寸和高效率.主要用在ADAS雷达系统,盲区检测(BSD),车道改变辅助(LCA),前/后两侧来车警告系统(F/RCTA),自动紧急制动(AEB),和自适应巡航控制系统(ACC).本文介绍了参考设计TIDA-020004主要特性,雷达模块框图,电路图,材料清单和PCB设计图.

This automotive radar reference design providescustomers with a tested 76-GHz to 81-GHz radarsensor module solution. The onboard power suppliesconvert the automotive battery input to the requiredrails for the radar analog front end (AFE), processors,and controller area networking with flexible data rate(CAN-FD) transceivers. After processing, the objectdata transmits over the included CAN-FD physicallayer (PHY).

Radar sensors are a requirement for many automotive safety systems. Locating these sensors in bumpersand side mirrors can be difficult. A very small sensor simplifies the process of meeting these marketdemands and provides a less expensive approach to meet such requirements. This reference designaddresses these concerns by combining a single-chip, 76- to 81-GHz automotiv..
