mmWave sensors support frequencies from 76 to 81GHz
Ultra-wideband millimeter wave (mmWave) sensors from Texas Instruments are now being shipped by Mouser Electronics. Said to be the industry's first single-chip, CMOS mmWave sensors in mass production, the devices support frequencies from 76 to 81GHz.
The sensors are self-contained, single-chip solutions based on frequency-modulated continuous wave (FMCW) radar technology.
The industrial IWR1642 and automotive AWR1642 sensors integrate entire mmWave blocks and analogue baseband signal chain for two transmitters and four receivers, an analogue-to-digital converter (ADC), programmable Arm Cortex-R4F microcontroller, and hardware accelerator, plus a high-performance DSP for radar signal processing.
The automotive-qualified AWR1642 sensors analyse and respond to an automobile’s nearby environment, resulting in improved safety and usability.
The device enables multimode radar for processing complex urban environments and short-range radar for detecting automobiles, motorcycles and other dynamic objects up to 80 meters away with high accuracy.
The industrial-focused IWR1642 sensors are ideal for building automation, traffic monitoring, gesture recognition, and more. The sensors are designed to accurately detect the angle, range and velocity of objects, even in adverse conditions such as rain, fog, smoke and ambient light.
The devices also support radar for transport, with the ability to detect moving vehicles at a distance of 60 meters with incoming velocities of up to 100 kilometers per hour.
