79 GHz Functions & Technology
Market Drivers for Advanced Driver Assistance
Legislation & Regulation
 EuroNCAP+ plans to include ADAS*
in 2014/ 2016
 NA NCAP & JNCAP: showing clear
hints to ADAS, e.g. @ safecar.org
 EU: LDW & emergency brake assist
mandatory for HDV** (2013)
Availability DA Functions
 Low Speed Active Braking and
Collision Warning already standard
in some cars
 Active Pedestrian protection
 Democratization of DA functions
(availability in compact car segment)
Consumer
Technology
 Consumer surveys indicating
willingness to buy
 EuroNCAP+ advanced and consumer
tests (e.g. ADAC) raise endconsumer awareness
+ New
car assessment program
 Radar and video dominating but no
dedicated sensor concept yet as
standard settled
 Need for sensor data fusion
 Cost/benefit ratio major focus
**HDV: Heavy Duty Vehicles

79 GHz Functions & Technology
• 76 GHz SiGe - Technology is in series production and radars have
been installed worldwide since 2009
• 76 GHz and 79 GHz technology is identical; some differences in
broadband antenna design and antenna technology
• Released components (MMICs, substrates, plastics) for 79 GHz
available
• Pre-series high resolution sensors are available for evaluation
• Cost situation today: 79 GHz is cost comparable with 24 GHz and will
gain at the same time higher performance
