[原创] TI AWR1642汽车短距离雷达(SRR)参考设计TIDEP－0092

TI公司的AWR1642是工作在76-81GHz频段的单片FMCW雷达传感器,采用低功耗的45nm的RFCMOS工艺,具有调频连续波(FMCW)收发器,集成了整数PLL,发送器,接收器,基带和A2D,有四个接收通路,2个发送通路,发送功率12.5dBm,76 - 77 GHz时的接收噪音14dB,77-81 GHz时的接收噪音15dB,采用基于ARM® Cortex®-R4F的无线电控制系统,具有内置的校验和自测,主要用在盲点检测,变道辅助,停车辅助,路口交通警报,占用检测,简单手势识别和车门开启应用.本文介绍了AWR1642主要特性,框图和应用电路与参考电路图,评估模块AWR1642BOOST主要特性以及采用评估模块的短距离雷达(SRR)参考设计TIDEP-0092主要特性和指标,框图,电路图和材料清单.

The AWR1642 device is an integrated single-chip FMCW radar sensor capable of operation in the 76- to81-GHz band. The device is built with TI’s low-power 45-nm RFCMOS process and enablesunprecedented levels of integration in an extremely small form factor. The AWR1642 is an ideal solutionfor low-power, self-monitored, ultra-accurate radar systems in the automotive space.
