Automotive Radar

Millions of automobiles worldwide carry Radar sensors designed by smartmicro. With over 20 years of experience in the design and development of automotive Radar driver assistance systems (ADAS), smartmicro has a long track record and is proud to offer 4th generation Radar technology today.

smartmicro has invented the Lane Change Assist Radar, started series development in 2003 and started high volume production in 2006 with partners. For Lane Change Assist (LCA) systems, it is today one of the top selling - and the leading technology worldwide. smartmicro is a specialist in corner radar (side/rear and side/front) applications like Blind Spot Detection (BSD), Rear Cross Traffic Assist (RCTA), Exit Assist and Rear Collision Warning (RCW).

Longer range Forward Looking sensors went in production in 2008. Today 76-77GHz sensors are manufactured for FCW, ACC, AEB and other functions.

Latest Products are 76-81GHz multi-mode high bandwidth sensors for Level 4 Automomous Driving, Parking Aid and general 360 Degree Applications.

Customers like Audi, Volkswagen, BMW, Mazda, Porsche, PSA and Hyundai/Kia 
use smartmicro technology.

The innovative UMRR (Universal Medium Range Radar) sensor platforms are flexible and scalable to allow low, medium and high performance solutions for many automotive applications.

ADAS Product Development

smartmicro delivers design-, development- and related engineering services and complete solutions  to many 1st tier automotive suppliers worldwide who manufacture such radar sensors on own production lines. We develop very competitive solutions - lowest BOM cost, high yield, ground breaking sensor performance. Quality and reliability of our products are mass-production ready. We are innovation. For over 15 years, for nearly 100 customers.

Smartmicro also runs an in-house production line comprising SMT, sensor assembly and automated end-of-line test equipment.

Automotive Standard Products - 4D/UHD Technology

See smartmicro's 360 degree 4D/UHD radars @76-81GHz designed for L4 autonomous driving. Four low cost, very compact, all-CMOS based sensors run in high resolution mode with some 5cm range accuracy. Note the interesting 3-dimensional shapes of all kind of objects which can be seen. The sensors also have other operational modes up to 120m range.
