Automotive Radar

Section Menu

Millions of automobiles wordwide carry Radar sensors designed by Smartmicro. With over 18 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 3rd and 4th generation Radar technology today.

Smartmicro has invented the Lane Change Assist Radar, started series development of it in 2003 and started high volume production in 2006 with a partner. For Lane Change Assist (LCA) systems, it is today one of the top selling - and the leading technology worldwide. See Side/Rear Applications, also for the shorter range Blind Spot Detection (BSD), Rear Cross Traffic Assistance (RCTA) and Exit Assistant applications. The Rear Collision Warning (RCW) function was brought to production in 2010.

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

Younger products under development are 77-81GHz high bandwidth sensors for Automomous Driving, Parking Aid and other 360 Degree Applications.

Because of the attractive cost/performance ratio of Smartmicro Radar designs, customers like Audi, Volkswagen, BMW, Mazda, Porsche, PSA and Hyundai already use Smartmicro technology. Together with many more customers the integration of our innovative Radars in new vehicle models is under continuous development.

 

Smartmicro offers design-, development- and related engineering services and complete solutions for 1st tier automotive suppliers, to allow manufacturing of Smartmicro technology on the supplier's manufacturing lines. 

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

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.

Combines low cost and medium to high performance.

High-end design with highest resolution in 3 domensions.
