Texas Instruments AWR1843 automotive radar sensor

Texas Instruments’ (TI) AWR1843 is an integrated single-chip frequency-modulated continuous-wave (FMCW) radar sensor capable of operation in the 76–81 GHz mmW spectrum. TI’s low-power, 45 nm RFCMOS process enables a monolithic implementation of a system with three transmit (TX) and four receive (RX) channels plus built-in phase lock loop (PLL) and analog-to-digital converters (ADCs).

The automotive radar sensor integrates a digital signal processor (DSP) subsystem, based on TI’s high-performance C674x DSP, for radar signal processing, as well as a built-in self-test (BIST) processor subsystem responsible for radio configuration, control and calibration. An onboard user-programmable Arm Cortex-R4F processor enables object tracking and classification, AUTOSAR and interface control.

The AEC-Q100 qualified, ultra-wideband mmWave sensor enables high levels of integration in a small form factor. It is suitable for low-power, self-monitored radar systems in the automotive space.
