Sensors
Steering Toward
Full Vehicle Autonomy
by Silviu Tuca
Radar scene emulation helps bridge the gap between
simulation and real-world testing of autonomous systems
for SAE Level 4 capability.
The vision of fully autonomous vehicles (SAE
Levels 4 and 5) is fast approaching. Making this vision
a reality requires automotive OEMs to move beyond
the current levels of vehicle autonomy to deliver on
the promise of highly efficient transportation systems,
more driver freedom and improved passenger safety.
While road testing is a vital part of the development
process, the cost, time and challenge of repeatability
makes relying on real-world road testing alone
unrealistic. Using this approach, it would take hundreds
of years for vehicles to be reliable enough to navigate
urban and rural roadways safely 100% of the time.
Additionally, current in-lab test solutions deliver
an incomplete view of driving scenarios and mask
the complexity of the real-world due to their limited
horizontal or vertical field-of-view (FoV), minimum
simulated distance, and number of echoes per simulated
target capabilities.
Keysight Technologies recognized this problem
in 2021 when it introduced its Radar Scene Emulator,
enabling OEMs to lab-test complex, real-world driving
scenarios while accelerating the overall speed of test. The
company has kept its technology apace with current gaps.
The full traffic-scene emulator combines hundreds of
miniature radio frequency (RF) front ends into a scalable
emulation screen representing up to 512 objects and
distances as close as 1.5 meter (4.9 ft.).
On the path to L4
Shifting testing of complex driving scenarios from the road
to the lab accelerates the speed of testing. For OEMs who
need to realize new advanced driver assistance systems
(ADAS) functionality - and for ADAS/autonomous
driving (AD) developers who value safety first - the
Radar Scene Emulator and Keysight's Autonomous Drive
Emulation platform provide a high level of resolution.
