Single-chip industrial radar sensor integrating a radar accelerator
The IWR1843 device from Texas Instruments is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operating in the 76 to 81GHz band with up to 4-GHz continuous chirp. The device is built with the low-power 45nm RFCMOS process from Texas Instruments. This solution enables high levels of integration in an extremely small form factor.
The IWR1843 is a solution for low-power, self-monitored, ultra-accurate radar systems in industrial applications, such as, building automation, factory automation, drones, material handling, traffic monitoring, and surveillance.
The IWR1843 device is a self-contained, single-chip solution that simplifies the implementation of mmWave sensors in the band of 76 to 81GHz. The IWR1843 includes a monolithic implementation of a 3TX, 4RX system with built-in PLL, and A2D converters. The IWR1843 also integrates a DSP subsystem, which contains a TI high-performance C674x DSP for the radar signal processing.
The device includes an ARM R4F-based processor subsystem, which is responsible for front-end configuration, control, and calibration. Simple programming model changes can enable a wide variety of sensor implementation with the possibility of dynamic reconfiguration for implementing a multimode sensor.
The Hardware Accelerator block (HWA) can perform radar processing and can help save MIPS on the DSP for higher-level algorithms. Additionally, the device is provided as a complete platform solution including TI reference designs, software drivers, sample configurations, API guides, training, and user documentation.
