OTSL Announces State-of-Art Millimeter-Wave Radar Simulator Product for Autonomous Driving
NAGOYA, Japan, June 17, 2022 /Kyodo JBN/ --

- Super Parallel Optimization Improves Simulation Performance over 10 Times -

OTSL Inc., a short-distance wireless system and embedded system developer and 
distributor, has announced a new 3D real-time millimeter-wave radar simulator 
for autonomous driving (*1), AMMWR2 (Advanced Millimeter Wave Radar Simulator 
2). Since introducing AMMWR to market in 2017 as the world's first sensor 
simulator software for autonomous driving that enables dynamic real-time 
simulation, OTSL has continued to invest aggressively in its development. With 
the announcement of AMMWR2, OTSL has manifested the leaps in functionality and 
performance achieved in this development. This product is planned to be 
marketed worldwide by the end of this year to automotive manufacturers, system 
supply manufacturers developing, designing and producing vehicle sensors, and 
semiconductor manufacturers developing sensor devices.

"With the global advance in application of autonomous driving, expectations are 
growing for advanced simulation technology capable of creating a virtual 
reproduction of all kinds of driving conditions and verifying and validating 
safety and accuracy. However, the current autonomous driving vehicle has only 
Level 2 or Level 3 functions under the SAE International standards," said Shoji 
Hatano, CEO, OTSL and OTSL Germany GmbH. "In order to achieve fully autonomous 
driving via system monitoring, Level 5 of the standards, it is essential to 
include simulation of potential accidents caused by electronic device defect 
and sensor failures. AMMWR2, announced on June 17, is the only millimeter-wave 
radar sensor simulator that covers from the electronic device level, including 
semiconductors and sensors, to the Autonomous Driving (AD) and Advanced Driver 
Assistance System (ADAS) simulation domain."

AMMWR2 uses the ray-tracing method (*2) using in the optics simulation field 
and unique reflection / diffraction models, applying a dedicated 
three-dimensional computer-generated map from Unreal Engine 4 (EPIC Games, 
Inc.) implementation of reflection and diffraction models of roads, roadside 
trees, streetlights, traffic signals, signs, and others to achieve real-time 
simulation of dynamic objects. Developing original measurement methods and 
creating reflection models from data obtained by the measurement enables 
accurate simulation of how radio wave from radar is reflected, considering even 
the shapes and materials of vehicles, pedestrians, traffic signals, signs, and 
other objects. By strengthened partnership with COSIDE (R) (*3), a SystemC AMS 
design and simulation tool from COSEDA Technologies GmbH for semiconductors 
supporting design from the circuit design to the system design level, an 
environment can be created in which simulation can be performed entirely in 
software without the need for any hardware, such as sensors or electronic 
control units (ECUs), or even the vehicle itself.

AMMWR2 features the following major update. These performance and function 
enhancements will further facilitate shorter development and testing lead times 
for manufacturers working on autonomous driving technologies.

- Accelerated the simulation engine through internal code optimization and 
super parallel processing techniques. This has improved the performance of 
simulations with ray tracing by a factor of 10 or more.

- By strengthening partnership with COSEDA Technologies GmbH which develops 
SystemC AMS design and simulation tool COSIDE (R), various radar can be used as 
custom models in addition to unique radar models based on automotive radar that 
Tier-1 provides with OEM, including Bosch's FR5CPEC and Continental's ARS540.

- AMMWR2 now supports integration with the open-source CARLA Simulator, which 
is used widely for autonomous driving algorithm development and testing.

AMMWR2 will be introduced at the ADAS & Autonomous Vehicle Technology Expo, an 
exhibition of autonomous driving technologies, to be held from June 21 to June 
23, 2022, in Stuttgart, Germany.

In order to strengthen its COSMOSIM (R) product family of 3D real-time sensor 
simulators for autonomous driving, including mainstay product AMMWR, OTSL 
established a local entity in Munich, Germany, in October 2019, where it 
relocated its development and sales center. Going forward, OTSL will continue 
to expand its business globally and help create superior simulation 
environments for autonomous driving.

(*1) Millimeter-wave radar: Technology to measure the distance, direction, and 
size of an object by radiating radio waves toward the object and measuring the 
reflected waves. Waves are radiated in the millimeter-wave band, with a 
wavelength from 1 mm to 10 mm and a frequency of 30 GHz to 300 GHz.

(*2) Ray-tracing method: A method based on geometrical optics, tracing light 
rays and electromagnetic waves to draw images observed at arbitrary points.

(*3) COSIDE (R): An "Electronic System Level Design" tool, developed by COSEDA 
Technologies GmbH, enables customers to optimize their advanced and complex 
designs faster, more efficiently and more cost-effectively.
