TI公司的IWR1443是是基于FMCW雷达技术的单片mmWave传感器,工作在76-81GHz频段,高达4GHz连续Chirp信号,包括有内置了PLL和A2D转换器的确3TX,4RX系统,完全可配置支持复杂FFT和CFAR检测的硬件加速器,以及两个基于ARM R4F处理器子系统:一个用来主控制和附加算法,另一个用来前端配置,控制和校准.发送功率+12dBm,主要用在测量范围,速度和角度的工业传感器,位移传感,液位探测雷达,场发射器,交通监测,接近检测,安全监控和工厂自动化安全卫士.本文介绍了IWR1443主要特性,功能框图,77GHz发送器参考设计TIDEP-0091主要特性,硬件框图和软件框图,以及参考设计TIDEP-0091框图,电路图,材料清单和IWR1443 EVMPCB设计图.

Single-Chip 76-to-81GHz mmWave Sensor Integrating MCU and Hardware Accelerator　The IWR1443 device is an integrated single-chip mmWave sensor based on FMCW radar technologycapable of operation in the 76- to 81-GHz band with up to 4 GHz continuous chirp. The device is built withTI’s low-power 45-nm RFCMOS process, and this solution enables unprecedented levels of integration inan extremely small form factor. The IWR1443 is an ideal solution for low-power, self-monitored, ultraaccurateradar systems in the industrial applications such as building automation, factory automation,drones, material handling, traffic monitoring, and surveillance.
