2020 Global Automotive Millimeterwave
Millimeter wave radar installations soared by 44.37 per cent year-on-year in 2019 and were available in more scenarios, encroaching on Lidar and ultrasonic.
Automotive radar wins popularity and gets increasingly installed. In 2019, 5.17 million mm-wave radars were installed in passenger cars in the Chinese market with an annualized spurt of 44.37 per cent, particularly 77GHz radar installations with an upsurge of 69.3 per cent from a year earlier.
Chinese carmakers have more radar installations than joint venture brands. For the newly launched models, Geely Geometry, WM Motor, BAIC ARCFOX, Chang’an, SAIC Roewe / MAXUS, FAW Hongqi, Xpeng and other homegrown brands all emphasize L2 / L2.5 / L3 autonomous driving technology and install more sensors including mmwave radar.
Well-known radar suppliers are promoting 77GHz radar vigorously, like the latest generation of mediumand long-range 77GHz radar launched by Bosch and Continental, and at the same time famous radar chip makers are mostly rolling out the 77GHzcentric chip generally in favor of the high modulation bandwidth 2GHz and with 3 transmitters and 4 receivers to detect farther.
The upcoming RXS816xPL is a highly integrated device that addresses the needs of 77-79 GHz radar for all safety-critical applications from automatic emergencybraking (AEB) to high-resolution radar in automated driving and that performs all functions of a radar front-end in a single device – from FMCW signal conditioning to generation of digital receive data output.
It resorts to high modulation bandwidth 2 GHz to realize precise distance measurement and simultaneous transmitter operation for MIMO, capable of detecting and identifying objects within 300 meters.

single-chip FMCW transceiver working in the 76- to 81-GHz band. The device has a tiny footprint and unprecedented integration and supports 5G bandwidth.
Simple programming model changes enable a wide variety of sensor implementation (short, medium, long range).
Additionally, the device is provided as a complete platform solution to reduce development costs.
MMW radar chip vendors have released suitable chips for more applications, especially in ultra-short range and short range.
Radar finds wider applications in scenarios like cockpit and occupant monitoring, automated parking, collaborative vehicle infrastructure system (CVIS) and intelligent transportation with the help of radar chips.
