APPLICATION NOTE
mmWave Automotive Radar and Antenna
System Development Using AWR Software
As modern vehicle development expands to include more and more sophisticated electronics,
automobile manufacturers are equipping their new models with advanced driver-assistance
system (ADAS) applications to obtain high safety ratings by increasing automotive safety.
Most road accidents occur due to human error and ADAS applications are proven to reduce
injuries and fatalities by alerting drivers to and assisting them with a variety of issues,
including collision avoidance and low tire pressure, using radar technology mostly focused
over the 76-81GHz spectrum. They perform over a range of applications, operating conditions,
and object detection challenges in order to provide reliable coverage over the range (distance)
and field of view (angle) as dictated by the particular driver-assist function.
Design Overview
This application note presents some of the challenges behind developing millimeter-wave (mmWave) radar systems and the
antenna array technologies for the next generation of smart cars and trucks. Examples will be presented demonstrating
how the Cadence
