This market growth will come from 4D radar and imaging radar.

“The first commercial car radar was introduced in 2000 for Daimler and BMW cars,” says Cedric Malakin of Yole. “In 2020 and 2021, leading radar suppliers launched their 5th generation radars. Modern automotive radar sensors inherit from this long cycle of evolution. So far, the upgrades have focused mainly on cost optimization and the form factor, which explains the trend towards integration that the industry is pursuing. ”

In addition to integration, RF performance has improved over time. Initially, radars worked with analog beamforming and mechanical control, before switching to digital beamforming (lighting the whole scene).

In the era of digital beamforming, MIMO techniques have been introduced to increase the aperture of the virtual antenna while maintaining a reasonable physical size.

Currently, MIMO scaling is available from the industry (0.2k to 2k pixels) as the baseline for achieving an angular resolution below 1 ° for image radars.

This comes with new challenges that need to be overcome in terms of signal processing and computing, which explains why the focus is shifting to deep learning and artificial intelligence.

The automotive radar market has attracted growing interest in the last few years. At the system level, the market is governed by six main levels 1: Continental, Bosch, Hella, Denso, Aptiv and Veoneer.

At the silicon level, NXP and Infineon share most of the market.

New players gain design success either at the system level with Magna, Mobis, Weifu, etc., or at the silicon level with Arbe, Uhnder and Vayyar.
