Automotive radar sensor covers 76 to 81GHz band
Summary
The AWR1843AOP provides engineers with exceptional levels of integration in an extremely small form factor, for low-power, self-monitored, ultra-accurate radar systems in the automotive sector. Built with Texas Instruments low-power 45-nm RFCMOS process, the AWR1843AOP integrates a DSP subsystem, combining high-performance C674x DSP for radar signal processing, with a BIST processor subsystem, responsible for radio configuration, control, and calibration, with a user-programmable Arm Cortex-R4F processor for automotive interfacing. The AWR1843AOPs hardware accelerator block (HWA) can perform radar processing and offloads of the DSP to execute higher level algorithms. Simple programming model changes enable a wide variety of sensor applications like door opening, parking, blind spot, and lane change applications, with dynamic reconfiguration for implementing a multimode sensor. Additionally, the device is provided as a complete platform solution including reference hardware design, software drivers, sample configurations, API guide, and user documentation.
